1,2,4,79,158,316
Greatest Common Factor
We found the factors 2,78,21,316 . The biggest common factor number is the GCF number.
So the greatest common factor 2,78,21,316 is 1.
Lets's calculate LCM of 51,57,501,930
3 | 51, 57, 501, 930 |
17, 19, 167, 310 |
∴ So the LCM of the given numbers is 3 x 17 x 19 x 167 x 310 = 50165130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50165130
Therefore, the GCF of Fractions 2/51,78/57,21/501,316/930 is 1/50165130
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 51,57,501,930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,57,501,930) = 3
common factors(in case of two or more numbers have common factors) = 9
GCF(51,57,501,930) x common factors =3 x 9 = 27
LCM(51,57,501,930) = ( 51 × 57 × 501 × 930 ) / 27
LCM(51,57,501,930) = 1354458510 / 27
LCM(51,57,501,930) = 50165130
