Greatest Common Factor

We found the factors 215,255 . The biggest common factor number is the GCF number.
So the greatest common factor 215,255 is 5.

Lets's calculate LCM of 70,265

5 70, 265
14, 53

∴ So the LCM of the given numbers is 5 x 14 x 53 = 3710

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/3710

Therefore, the GCF of Fractions 215/70,255/265 is 5/3710

Least Common Multiple of 70,265 with GCF Formula

Least Common Multiple of 70,265 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 70,265 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(70,265) = 5

common factors(in case of two or more numbers have common factors) = 1

GCF(70,265) x common factors =5 x 1 = 5

LCM(70,265) = ( 70 × 265 ) / 5

LCM(70,265) = 18550 / 5

LCM(70,265) = 3710
