List of positive integer factors of 973 that divides 973 without a remainder.
1,7,139,973
Greatest Common Factor
We found the factors 12,85,83,973 . The biggest common factor number is the GCF number.
So the greatest common factor 12,85,83,973 is 1.
Lets's calculate LCM of 84,28,52,85
2 | 84, 28, 52, 85 |
2 | 42, 14, 26, 85 |
7 | 21, 7, 13, 85 |
3, 1, 13, 85 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 3 x 1 x 13 x 85 = 92820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/92820
Therefore, the GCF of Fractions 12/84,85/28,83/52,973/85 is 1/92820
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 84,28,52,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(84,28,52,85) = 1
common factors(in case of two or more numbers have common factors) = 112
GCF(84,28,52,85) x common factors =1 x 112 = 112
LCM(84,28,52,85) = ( 84 × 28 × 52 × 85 ) / 112
LCM(84,28,52,85) = 10395840 / 112
LCM(84,28,52,85) = 92820
