Greatest Common Factor
We found the factors 749,221 . The biggest common factor number is the GCF number.
So the greatest common factor 749,221 is 1.
Lets's calculate LCM of 423,357
3 | 423, 357 |
141, 119 |
∴ So the LCM of the given numbers is 3 x 141 x 119 = 50337
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/50337
Therefore, the GCF of Fractions 749/423,221/357 is 1/50337
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 423,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(423,357) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(423,357) x common factors =3 x 1 = 3
LCM(423,357) = ( 423 × 357 ) / 3
LCM(423,357) = 151011 / 3
LCM(423,357) = 50337
