Greatest Common Factor

We found the factors 2,8,8,78 . The biggest common factor number is the GCF number.
So the greatest common factor 2,8,8,78 is 2.

Lets's calculate LCM of 47,35,30,828

2 47, 35, 30, 828
3 47, 35, 15, 414
5 47, 35, 5, 138
47, 7, 1, 138

∴ So the LCM of the given numbers is 2 x 3 x 5 x 47 x 7 x 1 x 138 = 1362060

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1362060

Therefore, the GCF of Fractions 2/47,8/35,8/30,78/828 is 2/1362060

Least Common Multiple of 47,35,30,828 with GCF Formula

Least Common Multiple of 47,35,30,828 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 47,35,30,828 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(47,35,30,828) = 1

common factors(in case of two or more numbers have common factors) = 30

GCF(47,35,30,828) x common factors =1 x 30 = 30

LCM(47,35,30,828) = ( 47 × 35 × 30 × 828 ) / 30

LCM(47,35,30,828) = 40861800 / 30

LCM(47,35,30,828) = 1362060
