Greatest Common Factor
We found the factors 638,985 . The biggest common factor number is the GCF number.
So the greatest common factor 638,985 is 1.
Lets's calculate LCM of 37,570
Given numbers has no common factors except 1. So, there LCM is their product i.e 21090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21090
Therefore, the GCF of Fractions 638/37,985/570 is 1/21090
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 37,570 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,570) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,570) x common factors =1 x 1 = 1
LCM(37,570) = ( 37 × 570 ) / 1
LCM(37,570) = 21090 / 1
LCM(37,570) = 21090
