Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 38/947,25/705
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 38/947,25/705, numerators are 38,25
Denominators are 947,705
The GCF of 38,25 is 1 .
LCM of 947,705 is 667635.
The greatest common factor of 38/947,25/705 = [GCF of 38,25]/[LCM of 947,705]= 1/667635
Therefore, the GCF of 38/947,25/705 is 1/667635.
To find the highest common factor of 38,25, we have to find the factors of both numbers and list the highest common factor.
The factors of 38 are 1, 2, 19, 38
The factors of 25 are 1, 5, 25
The HCF of 38,25 is 1.
Lets's calculate GCF of 38,25
∴ So GCF of numbers is 1 because of no common factors present between them.
Lets's calculate LCM of 947,705
Given numbers has no common factors except 1. So, there LCM is their product i.e 667635
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/667635
Therefore, the GCF of Fractions 38/947,25/705 is 1/667635
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 947,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(947,705) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(947,705) x common factors =1 x 1 = 1
LCM(947,705) = ( 947 × 705 ) / 1
LCM(947,705) = 667635 / 1
LCM(947,705) = 667635
