Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 7/58,5/33,30/58,85/222
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 7,5,30,85
Greatest Common Factor of Numerators i.e. GCF of 7,5,30,85 is 1 .
LCM of Denominators means LCM of 58,33,58,222 as per the given fractions.
LCM of 58,33,58,222 is 70818 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 7,5,30,85
∴ So GCF of numbers is 1 because of no common factors present between them.

Greatest Common Factor
We found the factors 7,5,30,85 . The biggest common factor number is the GCF number.
So the greatest common factor 7,5,30,85 is 1.
Lets's calculate LCM of 58,33,58,222
2 | 58, 33, 58, 222 |
3 | 29, 33, 29, 111 |
29 | 29, 11, 29, 37 |
1, 11, 1, 37 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 1 x 11 x 1 x 37 = 70818
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/70818
Therefore, the GCF of Fractions 7/58,5/33,30/58,85/222 is 1/70818
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 58,33,58,222 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,33,58,222) = 1
common factors(in case of two or more numbers have common factors) = 348
GCF(58,33,58,222) x common factors =1 x 348 = 348
LCM(58,33,58,222) = ( 58 × 33 × 58 × 222 ) / 348
LCM(58,33,58,222) = 24644664 / 348
LCM(58,33,58,222) = 70818
