So the greatest common factor 45,65,77,283 is 1.

Lets's calculate LCM of 62,70,23,70

2 62, 70, 23, 70
5 31, 35, 23, 35
7 31, 7, 23, 7
31, 1, 23, 1

∴ So the LCM of the given numbers is 2 x 5 x 7 x 31 x 1 x 23 x 1 = 49910

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/49910

Therefore, the GCF of Fractions 45/62,65/70,77/23,283/70 is 1/49910

Least Common Multiple of 62,70,23,70 with GCF Formula

Least Common Multiple of 62,70,23,70 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 62,70,23,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(62,70,23,70) = 1

common factors(in case of two or more numbers have common factors) = 140

GCF(62,70,23,70) x common factors =1 x 140 = 140

LCM(62,70,23,70) = ( 62 × 70 × 23 × 70 ) / 140

LCM(62,70,23,70) = 6987400 / 140

LCM(62,70,23,70) = 49910
