1,2,3,5,6,7,10,14,15,21,30,35,42,70,105,210
Greatest Common Factor
We found the factors 745,210 . The biggest common factor number is the GCF number.
So the greatest common factor 745,210 is 5.
Lets's calculate LCM of 264,378
2 | 264, 378 |
3 | 132, 189 |
44, 63 |
∴ So the LCM of the given numbers is 2 x 3 x 44 x 63 = 16632
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/16632
Therefore, the GCF of Fractions 745/264,210/378 is 5/16632
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 264,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(264,378) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(264,378) x common factors =6 x 1 = 6
LCM(264,378) = ( 264 × 378 ) / 6
LCM(264,378) = 99792 / 6
LCM(264,378) = 16632
