Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 504/64,864/625
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 504,864
Greatest Common Factor of Numerators i.e. GCF of 504,864 is 72 .
LCM of Denominators means LCM of 64,625 as per the given fractions.
LCM of 64,625 is 40000 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 504,864
2 | 504, 864 |
2 | 252, 432 |
2 | 126, 216 |
3 | 63, 108 |
3 | 21, 36 |
7, 12 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 3 x 3 = 72

1,2,3,4,6,8,9,12,16,18,24,27,32,36,48,54,72,96,108,144,216,288,432,864
Greatest Common Factor
We found the factors 504,864 . The biggest common factor number is the GCF number.
So the greatest common factor 504,864 is 72.
Lets's calculate LCM of 64,625
Given numbers has no common factors except 1. So, there LCM is their product i.e 40000
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 72/40000
Therefore, the GCF of Fractions 504/64,864/625 is 72/40000
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 64,625 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(64,625) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(64,625) x common factors =1 x 1 = 1
LCM(64,625) = ( 64 × 625 ) / 1
LCM(64,625) = 40000 / 1
LCM(64,625) = 40000
