Greatest Common Factor
We found the factors 61,343,491 . The biggest common factor number is the GCF number.
So the greatest common factor 61,343,491 is 1.
Lets's calculate LCM of 279,302,158
2 | 279, 302, 158 |
279, 151, 79 |
∴ So the LCM of the given numbers is 2 x 279 x 151 x 79 = 6656382
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6656382
Therefore, the GCF of Fractions 61/279,343/302,491/158 is 1/6656382
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 279,302,158 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(279,302,158) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(279,302,158) x common factors =1 x 2 = 2
LCM(279,302,158) = ( 279 × 302 × 158 ) / 2
LCM(279,302,158) = 13312764 / 2
LCM(279,302,158) = 6656382
