Greatest Common Factor
We found the factors 78,60,94,16 . The biggest common factor number is the GCF number.
So the greatest common factor 78,60,94,16 is 2.
Lets's calculate LCM of 74,58,13,157
2 | 74, 58, 13, 157 |
37, 29, 13, 157 |
∴ So the LCM of the given numbers is 2 x 37 x 29 x 13 x 157 = 4379986
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4379986
Therefore, the GCF of Fractions 78/74,60/58,94/13,16/157 is 2/4379986
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 74,58,13,157 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,58,13,157) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(74,58,13,157) x common factors =1 x 2 = 2
LCM(74,58,13,157) = ( 74 × 58 × 13 × 157 ) / 2
LCM(74,58,13,157) = 8759972 / 2
LCM(74,58,13,157) = 4379986
