Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 32/22,30/44,670/77
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 32,30,670
Greatest Common Factor of Numerators i.e. GCF of 32,30,670 is 2 .
LCM of Denominators means LCM of 22,44,77 as per the given fractions.
LCM of 22,44,77 is 308 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 32,30,670
2 | 32, 30, 670 |
16, 15, 335 |
∴ So the GCF of the given numbers is 2 = 2
Factors of 32
List of positive integer factors of 32 that divides 32 without a remainder.
1,2,4,8,16,32
Factors of 30
List of positive integer factors of 30 that divides 30 without a remainder.
1,2,3,5,6,10,15,30
Factors of 670
List of positive integer factors of 670 that divides 670 without a remainder.
1,2,5,10,67,134,335,670
Greatest Common Factor
We found the factors 32,30,670 . The biggest common factor number is the GCF number.
So the greatest common factor 32,30,670 is 2.
Lets's calculate LCM of 22,44,77
2 | 22, 44, 77 |
11 | 11, 22, 77 |
1, 2, 7 |
∴ So the LCM of the given numbers is 2 x 11 x 1 x 2 x 7 = 308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/308
Therefore, the GCF of Fractions 32/22,30/44,670/77 is 2/308
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 22,44,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(22,44,77) = 11
common factors(in case of two or more numbers have common factors) = 22
GCF(22,44,77) x common factors =11 x 22 = 242
LCM(22,44,77) = ( 22 × 44 × 77 ) / 242
LCM(22,44,77) = 74536 / 242
LCM(22,44,77) = 308
