Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 32/706,80/3942
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 32,80
Greatest Common Factor of Numerators i.e. GCF of 32,80 is 16 .
LCM of Denominators means LCM of 706,3942 as per the given fractions.
LCM of 706,3942 is 1391526 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 32,80
2 | 32, 80 |
2 | 16, 40 |
2 | 8, 20 |
2 | 4, 10 |
2, 5 |
∴ So the GCF of the given numbers is 2 x 2 x 2 x 2 = 16
Factors of 32
List of positive integer factors of 32 that divides 32 without a remainder.
1,2,4,8,16,32
Factors of 80
List of positive integer factors of 80 that divides 80 without a remainder.
1,2,4,5,8,10,16,20,40,80
Greatest Common Factor
We found the factors 32,80 . The biggest common factor number is the GCF number.
So the greatest common factor 32,80 is 16.
Lets's calculate LCM of 706,3942
2 | 706, 3942 |
353, 1971 |
∴ So the LCM of the given numbers is 2 x 353 x 1971 = 1391526
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/1391526
Therefore, the GCF of Fractions 32/706,80/3942 is 16/1391526
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 706,3942 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(706,3942) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(706,3942) x common factors =2 x 1 = 2
LCM(706,3942) = ( 706 × 3942 ) / 2
LCM(706,3942) = 2783052 / 2
LCM(706,3942) = 1391526
