1,5,13,25,65,169,325,845,4225
Greatest Common Factor
We found the factors 35,4225 . The biggest common factor number is the GCF number.
So the greatest common factor 35,4225 is 5.
Lets's calculate LCM of 780,5970
2 | 780, 5970 |
3 | 390, 2985 |
5 | 130, 995 |
26, 199 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 26 x 199 = 155220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/155220
Therefore, the GCF of Fractions 35/780,4225/5970 is 5/155220
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 780,5970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,5970) = 30
common factors(in case of two or more numbers have common factors) = 1
GCF(780,5970) x common factors =30 x 1 = 30
LCM(780,5970) = ( 780 × 5970 ) / 30
LCM(780,5970) = 4656600 / 30
LCM(780,5970) = 155220
