1,2,3,6,7,13,14,21,26,39,42,78,91,182,273,546
Greatest Common Factor
We found the factors 84,546 . The biggest common factor number is the GCF number.
So the greatest common factor 84,546 is 42.
Lets's calculate LCM of 642,765
3 | 642, 765 |
214, 255 |
∴ So the LCM of the given numbers is 3 x 214 x 255 = 163710
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 42/163710
Therefore, the GCF of Fractions 84/642,546/765 is 42/163710
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 642,765 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,765) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(642,765) x common factors =3 x 1 = 3
LCM(642,765) = ( 642 × 765 ) / 3
LCM(642,765) = 491130 / 3
LCM(642,765) = 163710
