Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 21/973,64/624
To find the GCF of fractions, we have to find the GCF of numerator numbers and LCM of denominator numbers. Its formula is given by
GCF of Fraction = Greatest Common Factor of Numerator/Least Common Multiple of Denominators
In the fractions 21/973,64/624, numerators are 21,64
Denominators are 973,624
The GCF of 21,64 is 1 .
LCM of 973,624 is 607152.
The greatest common factor of 21/973,64/624 = [GCF of 21,64]/[LCM of 973,624]= 1/607152
Therefore, the GCF of 21/973,64/624 is 1/607152.
To find the highest common factor of 21,64, we have to find the factors of both numbers and list the highest common factor.
The factors of 21 are 1, 3, 7, 21
The factors of 64 are 1, 2, 4, 8, 16, 32, 64
The HCF of 21,64 is 1.
Lets's calculate GCF of 21,64
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 21
:1,3,7,21
Now, list down the factors of 64
:1,2,4,8,16,32,64
Greatest Common Factor
We found the factors 21,64 . The biggest common factor number is the GCF number.
So the greatest common factor 21,64 is 1.
Lets's calculate LCM of 973,624
Given numbers has no common factors except 1. So, there LCM is their product i.e 607152
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/607152
Therefore, the GCF of Fractions 21/973,64/624 is 1/607152
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 973,624 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(973,624) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(973,624) x common factors =1 x 1 = 1
LCM(973,624) = ( 973 × 624 ) / 1
LCM(973,624) = 607152 / 1
LCM(973,624) = 607152
