Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
What is the GCF of 7/10,5/77,4/57,31/899?
Given fractions are 7/10,5/77,4/57,31/899
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 7/10,5/77,4/57,31/899, numerators are 7,5,4,31
Denominators are 10,77,57,899
The GCF of 7,5,4,31 is 1 .
LCM of 10,77,57,899 is 39457110.
The greatest common factor of 7/10,5/77,4/57,31/899 = [GCF of 7,5,4,31]/[LCM of 10,77,57,899]= 1/39457110
Therefore, the GCF of 7/10,5/77,4/57,31/899 is 1/39457110.
To find the highest common factor of 7,5,4,31, we have to find the factors of both numbers and list the highest common factor.
The factors of 7 are 1, 7
The factors of 5 are 1, 5
The factors of 4 are 1, 2, 4
The factors of 31 are 1, 31
The HCF of 7,5,4,31 is 1.
Lets's calculate GCF of 7,5,4,31
∴ So GCF of numbers is 1 because of no common factors present between them.

Lets's calculate LCM of 10,77,57,899
Given numbers has no common factors except 1. So, there LCM is their product i.e 39457110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39457110
Therefore, the GCF of Fractions 7/10,5/77,4/57,31/899 is 1/39457110
Least Common Multiple of 10,77,57,899 with GCF Formula
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 10,77,57,899 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,77,57,899) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(10,77,57,899) x common factors =1 x 1 = 1
LCM(10,77,57,899) = ( 10 × 77 × 57 × 899 ) / 1
LCM(10,77,57,899) = 39457110 / 1
LCM(10,77,57,899) = 39457110
