So the greatest common factor 56,38,813 is 1.
Lets's calculate LCM of 988,549,880
2 | 988, 549, 880 |
2 | 494, 549, 440 |
247, 549, 220 |
∴ So the LCM of the given numbers is 2 x 2 x 247 x 549 x 220 = 119330640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/119330640
Therefore, the GCF of Fractions 56/988,38/549,813/880 is 1/119330640
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 988,549,880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(988,549,880) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(988,549,880) x common factors =1 x 4 = 4
LCM(988,549,880) = ( 988 × 549 × 880 ) / 4
LCM(988,549,880) = 477322560 / 4
LCM(988,549,880) = 119330640
