1,3,19,57
Factors of 73
List of positive integer factors of 73 that divides 73 without a remainder.
1,73
Greatest Common Factor
We found the factors 39,91,57,73 . The biggest common factor number is the GCF number.
So the greatest common factor 39,91,57,73 is 1.
Lets's calculate LCM of 73,55,69,670
5 | 73, 55, 69, 670 |
73, 11, 69, 134 |
∴ So the LCM of the given numbers is 5 x 73 x 11 x 69 x 134 = 37122690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37122690
Therefore, the GCF of Fractions 39/73,91/55,57/69,73/670 is 1/37122690
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 73,55,69,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(73,55,69,670) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(73,55,69,670) x common factors =1 x 5 = 5
LCM(73,55,69,670) = ( 73 × 55 × 69 × 670 ) / 5
LCM(73,55,69,670) = 185613450 / 5
LCM(73,55,69,670) = 37122690
