Greatest Common Factor

We found the factors 85,82,93,276 . The biggest common factor number is the GCF number.
So the greatest common factor 85,82,93,276 is 1.

Lets's calculate LCM of 90,10,70,15

2 90, 10, 70, 15
3 45, 5, 35, 15
5 5, 5, 35, 15
1, 1, 7, 3

∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 1 x 7 x 3 = 630

Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/630

Therefore, the GCF of Fractions 85/90,82/10,93/70,276/15 is 1/630

Least Common Multiple of 90,10,70,15 with GCF Formula

Least Common Multiple of 90,10,70,15 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 90,10,70,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(90,10,70,15) = 5

common factors(in case of two or more numbers have common factors) = 300

GCF(90,10,70,15) x common factors =5 x 300 = 1500

LCM(90,10,70,15) = ( 90 × 10 × 70 × 15 ) / 1500

LCM(90,10,70,15) = 945000 / 1500

LCM(90,10,70,15) = 630
