:1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 769,620 . The biggest common factor number is the GCF number.
So the greatest common factor 769,620 is 1.
Lets's calculate LCM of 844,854
2 | 844, 854 |
422, 427 |
∴ So the LCM of the given numbers is 2 x 422 x 427 = 360388
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/360388
Therefore, the GCF of Fractions 769/844,620/854 is 1/360388
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 844,854 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(844,854) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(844,854) x common factors =2 x 1 = 2
LCM(844,854) = ( 844 × 854 ) / 2
LCM(844,854) = 720776 / 2
LCM(844,854) = 360388
