1,2,19,38,67,134,1273,2546
Greatest Common Factor
We found the factors 649,2546 . The biggest common factor number is the GCF number.
So the greatest common factor 649,2546 is 1.
Lets's calculate LCM of 390,755
5 | 390, 755 |
78, 151 |
∴ So the LCM of the given numbers is 5 x 78 x 151 = 58890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/58890
Therefore, the GCF of Fractions 649/390,2546/755 is 1/58890
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 390,755 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,755) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(390,755) x common factors =5 x 1 = 5
LCM(390,755) = ( 390 × 755 ) / 5
LCM(390,755) = 294450 / 5
LCM(390,755) = 58890
