Greatest Common Factor
We found the factors 30,91,87,62 . The biggest common factor number is the GCF number.
So the greatest common factor 30,91,87,62 is 1.
Lets's calculate LCM of 34,67,61,395
Given numbers has no common factors except 1. So, there LCM is their product i.e 54888410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/54888410
Therefore, the GCF of Fractions 30/34,91/67,87/61,62/395 is 1/54888410
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 34,67,61,395 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,67,61,395) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(34,67,61,395) x common factors =1 x 1 = 1
LCM(34,67,61,395) = ( 34 × 67 × 61 × 395 ) / 1
LCM(34,67,61,395) = 54888410 / 1
LCM(34,67,61,395) = 54888410
