1,31
Factors of 59
List of positive integer factors of 59 that divides 59 without a remainder.
1,59
Greatest Common Factor
We found the factors 20,45,31,59 . The biggest common factor number is the GCF number.
So the greatest common factor 20,45,31,59 is 1.
Lets's calculate LCM of 85,73,95,770
5 | 85, 73, 95, 770 |
17, 73, 19, 154 |
∴ So the LCM of the given numbers is 5 x 17 x 73 x 19 x 154 = 18155830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/18155830
Therefore, the GCF of Fractions 20/85,45/73,31/95,59/770 is 1/18155830
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 85,73,95,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,73,95,770) = 1
common factors(in case of two or more numbers have common factors) = 25
GCF(85,73,95,770) x common factors =1 x 25 = 25
LCM(85,73,95,770) = ( 85 × 73 × 95 × 770 ) / 25
LCM(85,73,95,770) = 453895750 / 25
LCM(85,73,95,770) = 18155830
