What is the LCM of 18 15 and 3?

The LCM of 3,18,15 3 , 18 , 15 is 2⋅3⋅3⋅5=90 2 ⋅ 3 ⋅ 3 ⋅ 5 = 90 .

What is the least common multiple of 12 15 and 18?

180
Answer: LCM of 12, 15, and 18 is 180.

What is the LCM of 12 and 18?

36
The LCM of 12 and 18 is 36. To find the LCM (least common multiple) of 12 and 18, we need to find the multiples of 12 and 18 (multiples of 12 = 12, 24, 36, 48; multiples of 18 = 18, 36, 54, 72) and choose the smallest multiple that is exactly divisible by 12 and 18, i.e., 36.

What is the LCM of 15 and 18 using prime factorization?

LCM of 15 and 18 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 21 × 32 × 51 = 90. Hence, the LCM of 15 and 18 by prime factorization is 90.

What is the LCM of 18?

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88 . . . Next, we list the first several multiples of eighteen: 18, 36, 54, 72, 90, 108, 126, 144 . . . By comparing the multiples of eight and eighteen, we can see that the smallest one that they share is 72.

How do you find the product of HCF and LCM?

Both HCF and LCM of given numbers can be found by using two methods; they are division method and prime factorization. The product of LCM and HCF of any two given natural numbers is equivalent to the product of the given numbers. Suppose A and B are two numbers, then.

What is the product of HCF and lcm of 270?

HCF of two numbers is 3 and LCM of those numbers is 90. Now product of HCF and LCM = 270. Is there anyway to find out those numbers? Now find the factors of 270 and verify Y is for yes and N is for no (3, 90), (6, 45), (9, 30) and (15, 18). All the above mentioned pairs of numbers have 3 as HCF and 90 as LCM.

What is the LCM of 3 8 times HCF?

LCM × HCF = Product of the Numbers. Suppose A and B are two numbers, then. LCM (A & B) × HCF (A & B) = A × B. Example: If 3 and 8 are two numbers. LCM (3,8) = 24. HCF (3,8) = 1. LCM (3,8) x HCF (3,8) = 24 x 1 = 24. Also, 3 x 8 = 24. Hence, proved.

How do you find the product of two numbers?

Product of two number = (HCF of the two number) × (LCM of the two numbers) If in case you take the two numbers as m and n, then the HCF and LCM formula states that as below: m × n = HCF (m, n) × LCM (m, n) Using the given above formulas, you can calculate the HCF or LCM if you know one of them and the two numbers.
