Greatest Common Factor

We found the factors 14,28,77,27 . The biggest common factor number is the GCF number.
So the greatest common factor 14,28,77,27 is 1.

Lets's calculate LCM of 78,70,98,35

2 78, 70, 98, 35
5 39, 35, 49, 35
7 39, 7, 49, 7
39, 1, 1, 7

∴ So the LCM of the given numbers is 2 x 5 x 7 x 39 x 1 x 1 x 7 = 19110

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19110

Therefore, the GCF of Fractions 14/78,28/70,77/98,27/35 is 1/19110

Least Common Multiple of 78,70,98,35 with GCF Formula

Least Common Multiple of 78,70,98,35 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 78,70,98,35 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(78,70,98,35) = 1

common factors(in case of two or more numbers have common factors) = 980

GCF(78,70,98,35) x common factors =1 x 980 = 980

LCM(78,70,98,35) = ( 78 × 70 × 98 × 35 ) / 980

LCM(78,70,98,35) = 18727800 / 980

LCM(78,70,98,35) = 19110
