So the greatest common factor 700,391,689 is 1.


Lets's calculate LCM of 40,42,600

2 40, 42, 600
2 20, 21, 300
2 10, 21, 150
3 5, 21, 75
5 5, 7, 25
1, 7, 5

∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 1 x 7 x 5 = 4200

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4200

Therefore, the GCF of Fractions 700/40,391/42,689/600 is 1/4200

Least Common Multiple of 40,42,600 with GCF Formula

Least Common Multiple of 40,42,600 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 40,42,600 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,42,600) = 2

common factors(in case of two or more numbers have common factors) = 120

GCF(40,42,600) x common factors =2 x 120 = 240

LCM(40,42,600) = ( 40 × 42 × 600 ) / 240

LCM(40,42,600) = 1008000 / 240

LCM(40,42,600) = 4200
