# Find the Lcm and Hcf of the Following Integers by Applying the Prime Factorisation Method: 40, 36 and 126 - Mathematics

Numerical

Find the LCM and HCF of the following integers by applying the prime factorisation method:

40, 36 and 126

#### Solution

40, 36 and 126

Let us first find the factors of 40, 36 and 126

40=2^2xx5

36=2^2xx3^2

126=2xx3^3xx7

L.C.M of 40 ,36 and 126 = 2^2xx3^2xx5xx7

L.C.M of 40,36 and 126 =2520

H.C.F of 40,36 and 126 =2
