Question

L.c.m of 10,15,35,85​

Answer 1

Answer:

Least Common Multiple of 15 and 35 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 15 and 35, than apply into the LCM equation.

GCF(15,35) = 5

LCM(15,35) = ( 15 × 35) / 5

LCM(15,35) = 525 / 5

LCM(15,35) = 105

Prime factors of 35 are 5, 7. Prime factorization of 35 in exponential form is:

35 = 51 × 71

Now multiplying the highest exponent prime factors to calculate the LCM of 15 and 35.

LCM(15,35) = 31 × 51 × 71

LCM(15,35) = 105
