Greatest Common Factor
We found the factors 862,407,211 . The biggest common factor number is the GCF number.
So the greatest common factor 862,407,211 is 1.
Lets's calculate LCM of 72,63,378
2 | 72, 63, 378 |
3 | 36, 63, 189 |
3 | 12, 21, 63 |
7 | 4, 7, 21 |
4, 1, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 4 x 1 x 3 = 1512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1512
Therefore, the GCF of Fractions 862/72,407/63,211/378 is 1/1512
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 72,63,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,63,378) = 9
common factors(in case of two or more numbers have common factors) = 126
GCF(72,63,378) x common factors =9 x 126 = 1134
LCM(72,63,378) = ( 72 × 63 × 378 ) / 1134
LCM(72,63,378) = 1714608 / 1134
LCM(72,63,378) = 1512
