Greatest Common Factor
We found the factors 570,210 . The biggest common factor number is the GCF number.
So the greatest common factor 570,210 is 30.
Lets's calculate LCM of 156,510
2 | 156, 510 |
3 | 78, 255 |
26, 85 |
∴ So the LCM of the given numbers is 2 x 3 x 26 x 85 = 13260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 30/13260
Therefore, the GCF of Fractions 570/156,210/510 is 30/13260
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 156,510 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(156,510) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(156,510) x common factors =6 x 1 = 6
LCM(156,510) = ( 156 × 510 ) / 6
LCM(156,510) = 79560 / 6
LCM(156,510) = 13260
