:1,2,3,4,5,6,10,12,15,20,30,60,127,254,381,508,635,762,1270,1524,1905,2540,3810,7620
Greatest Common Factor
We found the factors 2643,7620 . The biggest common factor number is the GCF number.
So the greatest common factor 2643,7620 is 3.
Lets's calculate LCM of 456,9245
Given numbers has no common factors except 1. So, there LCM is their product i.e 4215720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4215720
Therefore, the GCF of Fractions 2643/456,7620/9245 is 3/4215720
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 456,9245 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(456,9245) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(456,9245) x common factors =1 x 1 = 1
LCM(456,9245) = ( 456 × 9245 ) / 1
LCM(456,9245) = 4215720 / 1
LCM(456,9245) = 4215720
