So the greatest common factor 56,979,658 is 1.
Lets's calculate LCM of 70,73,318
2 | 70, 73, 318 |
35, 73, 159 |
∴ So the LCM of the given numbers is 2 x 35 x 73 x 159 = 812490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/812490
Therefore, the GCF of Fractions 56/70,979/73,658/318 is 1/812490
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 70,73,318 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,73,318) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(70,73,318) x common factors =1 x 2 = 2
LCM(70,73,318) = ( 70 × 73 × 318 ) / 2
LCM(70,73,318) = 1624980 / 2
LCM(70,73,318) = 812490
