Greatest Common Factor
We found the factors 25,391,968 . The biggest common factor number is the GCF number.
So the greatest common factor 25,391,968 is 1.
Lets's calculate LCM of 51,44,648
2 | 51, 44, 648 |
2 | 51, 22, 324 |
3 | 51, 11, 162 |
17, 11, 54 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 17 x 11 x 54 = 121176
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/121176
Therefore, the GCF of Fractions 25/51,391/44,968/648 is 1/121176
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 51,44,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,44,648) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(51,44,648) x common factors =1 x 12 = 12
LCM(51,44,648) = ( 51 × 44 × 648 ) / 12
LCM(51,44,648) = 1454112 / 12
LCM(51,44,648) = 121176
