Factors of 76
List of positive integer factors of 76 that divides 76 without a remainder.
1,2,4,19,38,76
Greatest Common Factor
We found the factors 76,83,94,76 . The biggest common factor number is the GCF number.
So the greatest common factor 76,83,94,76 is 1.
Lets's calculate LCM of 56,20,91,38
2 | 56, 20, 91, 38 |
2 | 28, 10, 91, 19 |
7 | 14, 5, 91, 19 |
2, 5, 13, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 2 x 5 x 13 x 19 = 69160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/69160
Therefore, the GCF of Fractions 76/56,83/20,94/91,76/38 is 1/69160
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 56,20,91,38 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,20,91,38) = 1
common factors(in case of two or more numbers have common factors) = 56
GCF(56,20,91,38) x common factors =1 x 56 = 56
LCM(56,20,91,38) = ( 56 × 20 × 91 × 38 ) / 56
LCM(56,20,91,38) = 3872960 / 56
LCM(56,20,91,38) = 69160
