What is the GCF of 7/34,6/85,3/31,51/403?
Given fractions are 7/34,6/85,3/31,51/403
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 7/34,6/85,3/31,51/403, numerators are 7,6,3,51
Denominators are 34,85,31,403
The GCF of 7,6,3,51 is 1 .
LCM of 34,85,31,403 is 68510.
The greatest common factor of 7/34,6/85,3/31,51/403 = [GCF of 7,6,3,51]/[LCM of 34,85,31,403]= 1/68510
Therefore, the GCF of 7/34,6/85,3/31,51/403 is 1/68510.
To find the highest common factor of 7,6,3,51, we have to find the factors of both numbers and list the highest common factor.
The factors of 7 are 1, 7
The factors of 6 are 1, 2, 3, 6
The factors of 3 are 1, 3
The factors of 51 are 1, 3, 17, 51
The HCF of 7,6,3,51 is 1.
Lets's calculate GCF of 7,6,3,51
∴ So GCF of numbers is 1 because of no common factors present between them.

So the greatest common factor 7,6,3,51 is 1.
Lets's calculate LCM of 34,85,31,403
| 17 | 34, 85, 31, 403 |
| 31 | 2, 5, 31, 403 |
| 2, 5, 1, 13 |
∴ So the LCM of the given numbers is 17 x 31 x 2 x 5 x 1 x 13 = 68510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/68510
Therefore, the GCF of Fractions 7/34,6/85,3/31,51/403 is 1/68510
Least Common Multiple of 34,85,31,403 with GCF Formula
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 34,85,31,403 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,85,31,403) = 1
common factors(in case of two or more numbers have common factors) = 527
GCF(34,85,31,403) x common factors =1 x 527 = 527
LCM(34,85,31,403) = ( 34 × 85 × 31 × 403 ) / 527
LCM(34,85,31,403) = 36104770 / 527
LCM(34,85,31,403) = 68510
