Greatest Common Factor
We found the factors 88,40,42,256 . The biggest common factor number is the GCF number.
So the greatest common factor 88,40,42,256 is 2.
Lets's calculate LCM of 22,28,34,61
2 | 22, 28, 34, 61 |
11, 14, 17, 61 |
∴ So the LCM of the given numbers is 2 x 11 x 14 x 17 x 61 = 319396
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/319396
Therefore, the GCF of Fractions 88/22,40/28,42/34,256/61 is 2/319396
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 22,28,34,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,28,34,61) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(22,28,34,61) x common factors =1 x 4 = 4
LCM(22,28,34,61) = ( 22 × 28 × 34 × 61 ) / 4
LCM(22,28,34,61) = 1277584 / 4
LCM(22,28,34,61) = 319396
