Greatest Common Factor
We found the factors 359,515 . The biggest common factor number is the GCF number.
So the greatest common factor 359,515 is 1.
Lets's calculate LCM of 672,170
2 | 672, 170 |
336, 85 |
∴ So the LCM of the given numbers is 2 x 336 x 85 = 57120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57120
Therefore, the GCF of Fractions 359/672,515/170 is 1/57120
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 672,170 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(672,170) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(672,170) x common factors =2 x 1 = 2
LCM(672,170) = ( 672 × 170 ) / 2
LCM(672,170) = 114240 / 2
LCM(672,170) = 57120
