Greatest Common Factor
We found the factors 42,51,17,60 . The biggest common factor number is the GCF number.
So the greatest common factor 42,51,17,60 is 1.
Lets's calculate LCM of 67,89,91,188
Given numbers has no common factors except 1. So, there LCM is their product i.e 102015004
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/102015004
Therefore, the GCF of Fractions 42/67,51/89,17/91,60/188 is 1/102015004
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 67,89,91,188 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,89,91,188) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,89,91,188) x common factors =1 x 1 = 1
LCM(67,89,91,188) = ( 67 × 89 × 91 × 188 ) / 1
LCM(67,89,91,188) = 102015004 / 1
LCM(67,89,91,188) = 102015004
Here are some samples of GCF of Fractions calculations.
