1,2,4871,9742
Greatest Common Factor
We found the factors 639,9742 . The biggest common factor number is the GCF number.
So the greatest common factor 639,9742 is 1.
Lets's calculate LCM of 620,2755
5 | 620, 2755 |
124, 551 |
∴ So the LCM of the given numbers is 5 x 124 x 551 = 341620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/341620
Therefore, the GCF of Fractions 639/620,9742/2755 is 1/341620
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 620,2755 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,2755) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(620,2755) x common factors =5 x 1 = 5
LCM(620,2755) = ( 620 × 2755 ) / 5
LCM(620,2755) = 1708100 / 5
LCM(620,2755) = 341620
