Greatest Common Factor
We found the factors 129,100,978 . The biggest common factor number is the GCF number.
So the greatest common factor 129,100,978 is 1.
Lets's calculate LCM of 49,74,696
2 | 49, 74, 696 |
49, 37, 348 |
∴ So the LCM of the given numbers is 2 x 49 x 37 x 348 = 1261848
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1261848
Therefore, the GCF of Fractions 129/49,100/74,978/696 is 1/1261848
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 49,74,696 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,74,696) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(49,74,696) x common factors =1 x 2 = 2
LCM(49,74,696) = ( 49 × 74 × 696 ) / 2
LCM(49,74,696) = 2523696 / 2
LCM(49,74,696) = 1261848
