Greatest Common Factor
We found the factors 7,42,30,632 . The biggest common factor number is the GCF number.
So the greatest common factor 7,42,30,632 is 1.
Lets's calculate LCM of 39,80,413,233
Given numbers has no common factors except 1. So, there LCM is their product i.e 300234480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/300234480
Therefore, the GCF of Fractions 7/39,42/80,30/413,632/233 is 1/300234480
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 39,80,413,233 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,80,413,233) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(39,80,413,233) x common factors =1 x 1 = 1
LCM(39,80,413,233) = ( 39 × 80 × 413 × 233 ) / 1
LCM(39,80,413,233) = 300234480 / 1
LCM(39,80,413,233) = 300234480
