So the greatest common factor 50,90,88,642 is 2.
Lets's calculate LCM of 71,63,96,79
3 | 71, 63, 96, 79 |
71, 21, 32, 79 |
∴ So the LCM of the given numbers is 3 x 71 x 21 x 32 x 79 = 11307744
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/11307744
Therefore, the GCF of Fractions 50/71,90/63,88/96,642/79 is 2/11307744
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 71,63,96,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,63,96,79) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(71,63,96,79) x common factors =1 x 3 = 3
LCM(71,63,96,79) = ( 71 × 63 × 96 × 79 ) / 3
LCM(71,63,96,79) = 33923232 / 3
LCM(71,63,96,79) = 11307744
