So the greatest common factor 68,45,40,33 is 1.

Lets's calculate LCM of 42,69,49,700

2 42, 69, 49, 700
3 21, 69, 49, 350
7 7, 23, 49, 350
1, 23, 7, 50

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 23 x 7 x 50 = 338100

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/338100

Therefore, the GCF of Fractions 68/42,45/69,40/49,33/700 is 1/338100

Least Common Multiple of 42,69,49,700 with GCF Formula

Least Common Multiple of 42,69,49,700 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 42,69,49,700 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(42,69,49,700) = 1

common factors(in case of two or more numbers have common factors) = 294

GCF(42,69,49,700) x common factors =1 x 294 = 294

LCM(42,69,49,700) = ( 42 × 69 × 49 × 700 ) / 294

LCM(42,69,49,700) = 99401400 / 294

LCM(42,69,49,700) = 338100
