So the greatest common factor 77,71,20,10 is 1.
Lets's calculate LCM of 56,98,88,415
2 | 56, 98, 88, 415 |
2 | 28, 49, 44, 415 |
2 | 14, 49, 22, 415 |
7 | 7, 49, 11, 415 |
1, 7, 11, 415 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 1 x 7 x 11 x 415 = 1789480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1789480
Therefore, the GCF of Fractions 77/56,71/98,20/88,10/415 is 1/1789480
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 56,98,88,415 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,98,88,415) = 1
common factors(in case of two or more numbers have common factors) = 112
GCF(56,98,88,415) x common factors =1 x 112 = 112
LCM(56,98,88,415) = ( 56 × 98 × 88 × 415 ) / 112
LCM(56,98,88,415) = 200421760 / 112
LCM(56,98,88,415) = 1789480
