Greatest Common Factor
We found the factors 747,129,295 . The biggest common factor number is the GCF number.
So the greatest common factor 747,129,295 is 1.
Lets's calculate LCM of 11,78,980
| 2 | 11, 78, 980 |
| 11, 39, 490 |
∴ So the LCM of the given numbers is 2 x 11 x 39 x 490 = 420420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/420420
Therefore, the GCF of Fractions 747/11,129/78,295/980 is 1/420420
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 11,78,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,78,980) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(11,78,980) x common factors =1 x 2 = 2
LCM(11,78,980) = ( 11 × 78 × 980 ) / 2
LCM(11,78,980) = 840840 / 2
LCM(11,78,980) = 420420
