Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 90/92,79/42,830/76
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 90,79,830
Greatest Common Factor of Numerators i.e. GCF of 90,79,830 is 1 .
LCM of Denominators means LCM of 92,42,76 as per the given fractions.
LCM of 92,42,76 is 36708 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 90,79,830
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 90
List of positive integer factors of 90 that divides 90 without a remainder.
1,2,3,5,6,9,10,15,18,30,45,90
Factors of 79

1,79
Factors of 830
List of positive integer factors of 830 that divides 830 without a remainder.
1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 90,79,830 . The biggest common factor number is the GCF number.
So the greatest common factor 90,79,830 is 1.
Lets's calculate LCM of 92,42,76
2 | 92, 42, 76 |
2 | 46, 21, 38 |
23, 21, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 23 x 21 x 19 = 36708
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36708
Therefore, the GCF of Fractions 90/92,79/42,830/76 is 1/36708
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 92,42,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,42,76) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(92,42,76) x common factors =2 x 4 = 8
LCM(92,42,76) = ( 92 × 42 × 76 ) / 8
LCM(92,42,76) = 293664 / 8
LCM(92,42,76) = 36708
