Greatest Common Factor
We found the factors 87,1247 . The biggest common factor number is the GCF number.
So the greatest common factor 87,1247 is 29.
Lets's calculate LCM of 146,6180
2 | 146, 6180 |
73, 3090 |
∴ So the LCM of the given numbers is 2 x 73 x 3090 = 451140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 29/451140
Therefore, the GCF of Fractions 87/146,1247/6180 is 29/451140
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 146,6180 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(146,6180) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(146,6180) x common factors =2 x 1 = 2
LCM(146,6180) = ( 146 × 6180 ) / 2
LCM(146,6180) = 902280 / 2
LCM(146,6180) = 451140
