Find the LCM and HCF of the following integers by applying the prime factorisation method:
40, 36 and 126
उत्तर
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
