Greatest Common Factor
We found the factors 49,38,28,56 . The biggest common factor number is the GCF number.
So the greatest common factor 49,38,28,56 is 1.
Lets's calculate LCM of 73,73,79,784
73 | 73, 73, 79, 784 |
1, 1, 79, 784 |
∴ So the LCM of the given numbers is 73 x 1 x 1 x 79 x 784 = 4521328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4521328
Therefore, the GCF of Fractions 49/73,38/73,28/79,56/784 is 1/4521328
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 73,73,79,784 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,73,79,784) = 1
common factors(in case of two or more numbers have common factors) = 73
GCF(73,73,79,784) x common factors =1 x 73 = 73
LCM(73,73,79,784) = ( 73 × 73 × 79 × 784 ) / 73
LCM(73,73,79,784) = 330056944 / 73
LCM(73,73,79,784) = 4521328
