So the greatest common factor 621,781 is 1.
Lets's calculate LCM of 992,992
2 | 992, 992 |
2 | 496, 496 |
2 | 248, 248 |
2 | 124, 124 |
2 | 62, 62 |
31 | 31, 31 |
1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 31 x 1 x 1 = 992
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/992
Therefore, the GCF of Fractions 621/992,781/992 is 1/992
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 992,992 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(992,992) = 992
common factors(in case of two or more numbers have common factors) = 1
GCF(992,992) x common factors =992 x 1 = 992
LCM(992,992) = ( 992 × 992 ) / 992
LCM(992,992) = 984064 / 992
LCM(992,992) = 992
