Greatest Common Factor
We found the factors 98,93,31,78 . The biggest common factor number is the GCF number.
So the greatest common factor 98,93,31,78 is 1.
Lets's calculate LCM of 77,67,48,61
Given numbers has no common factors except 1. So, there LCM is their product i.e 15105552
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15105552
Therefore, the GCF of Fractions 98/77,93/67,31/48,78/61 is 1/15105552
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 77,67,48,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,67,48,61) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,67,48,61) x common factors =1 x 1 = 1
LCM(77,67,48,61) = ( 77 × 67 × 48 × 61 ) / 1
LCM(77,67,48,61) = 15105552 / 1
LCM(77,67,48,61) = 15105552
Here are some samples of GCF of Fractions calculations.
