So the greatest common factor 632,238 is 2.
Lets's calculate LCM of 651,455
7 | 651, 455 |
93, 65 |
∴ So the LCM of the given numbers is 7 x 93 x 65 = 42315
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/42315
Therefore, the GCF of Fractions 632/651,238/455 is 2/42315
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 651,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(651,455) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(651,455) x common factors =7 x 1 = 7
LCM(651,455) = ( 651 × 455 ) / 7
LCM(651,455) = 296205 / 7
LCM(651,455) = 42315
