Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 520/66,312/972
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 520,312
Greatest Common Factor of Numerators i.e. GCF of 520,312 is 104 .
LCM of Denominators means LCM of 66,972 as per the given fractions.
LCM of 66,972 is 10692 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 520,312
2 | 520, 312 |
2 | 260, 156 |
2 | 130, 78 |
13 | 65, 39 |
5, 3 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 13 = 104

1,2,4,5,8,10,13,20,26,40,52,65,104,130,260,520
Factors of 312
List of positive integer factors of 312 that divides 312 without a remainder.
1,2,3,4,6,8,12,13,24,26,39,52,78,104,156,312
Greatest Common Factor
We found the factors 520,312 . The biggest common factor number is the GCF number.
So the greatest common factor 520,312 is 104.
Lets's calculate LCM of 66,972
2 | 66, 972 |
3 | 33, 486 |
11, 162 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 162 = 10692
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 104/10692
Therefore, the GCF of Fractions 520/66,312/972 is 104/10692
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 66,972 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(66,972) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(66,972) x common factors =6 x 1 = 6
LCM(66,972) = ( 66 × 972 ) / 6
LCM(66,972) = 64152 / 6
LCM(66,972) = 10692
