Question

what is lcm and hcf of 24,15,36

Answer 1

Answer:

LCM= 360 and HCF= 3

Step-by-step explanation:

L.C.M and H.C.F are found by factorization method.

$24=2^{3}\:*\:3\\\\15= 3\:*\:5\\\\36= 2^2\:*\:3^2$

Therefore,

$L.C.M=2^3\:*\:3^2\:*\:5=8\:*\:9\:*\:5=360\\\\H.C.F= 3$

Answer 2

Answer: LCM- 360 and HCF- 3

Step-by-step explanation:

To find the LCM and HCF, first we need to find the factors of the three numbers.

The factors of 24 are 1,2,2,2,3

The factors of 15 are 1,3,5

The factors of 36 are 1,2,2,3,3

First, finding out the HCF which stands for Highest Common Factor:

The common factors of the three numbers are 1 and 3 but since we need the highest common factor so the HCF is 3.

LCM stands for lowest common multiple so on factorizing the three numbers together, we get the common multiple as 1,2,2,2,3,3,5 which comes to 360.
