Lets's calculate LCM of 780,6625
5 | 780, 6625 |
156, 1325 |
∴ So the LCM of the given numbers is 5 x 156 x 1325 = 1033500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/1033500
Therefore, the GCF of Fractions 27/780,2439/6625 is 9/1033500
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 780,6625 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,6625) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(780,6625) x common factors =5 x 1 = 5
LCM(780,6625) = ( 780 × 6625 ) / 5
LCM(780,6625) = 5167500 / 5
LCM(780,6625) = 1033500
