Greatest Common Factor
We found the factors 30,59,57,64 . The biggest common factor number is the GCF number.
So the greatest common factor 30,59,57,64 is 1.
Lets's calculate LCM of 67,92,92,57
2 | 67, 92, 92, 57 |
2 | 67, 46, 46, 57 |
23 | 67, 23, 23, 57 |
67, 1, 1, 57 |
∴ So the LCM of the given numbers is 2 x 2 x 23 x 67 x 1 x 1 x 57 = 351348
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/351348
Therefore, the GCF of Fractions 30/67,59/92,57/92,64/57 is 1/351348
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 67,92,92,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,92,92,57) = 1
common factors(in case of two or more numbers have common factors) = 92
GCF(67,92,92,57) x common factors =1 x 92 = 92
LCM(67,92,92,57) = ( 67 × 92 × 92 × 57 ) / 92
LCM(67,92,92,57) = 32324016 / 92
LCM(67,92,92,57) = 351348
