Greatest Common Factor
We found the factors 705,763 . The biggest common factor number is the GCF number.
So the greatest common factor 705,763 is 1.
Lets's calculate LCM of 604,642
2 | 604, 642 |
302, 321 |
∴ So the LCM of the given numbers is 2 x 302 x 321 = 193884
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/193884
Therefore, the GCF of Fractions 705/604,763/642 is 1/193884
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 604,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(604,642) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(604,642) x common factors =2 x 1 = 2
LCM(604,642) = ( 604 × 642 ) / 2
LCM(604,642) = 387768 / 2
LCM(604,642) = 193884
