So the greatest common factor 60,28,88,68 is 4.
Lets's calculate LCM of 57,19,67,639
3 | 57, 19, 67, 639 |
19 | 19, 19, 67, 213 |
1, 1, 67, 213 |
∴ So the LCM of the given numbers is 3 x 19 x 1 x 1 x 67 x 213 = 813447
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/813447
Therefore, the GCF of Fractions 60/57,28/19,88/67,68/639 is 4/813447
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 57,19,67,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,19,67,639) = 1
common factors(in case of two or more numbers have common factors) = 57
GCF(57,19,67,639) x common factors =1 x 57 = 57
LCM(57,19,67,639) = ( 57 × 19 × 67 × 639 ) / 57
LCM(57,19,67,639) = 46366479 / 57
LCM(57,19,67,639) = 813447
