:1,2,4,8,17,34,68,136
Greatest Common Factor
We found the factors 380,136 . The biggest common factor number is the GCF number.
So the greatest common factor 380,136 is 4.
Lets's calculate LCM of 975,830
5 | 975, 830 |
195, 166 |
∴ So the LCM of the given numbers is 5 x 195 x 166 = 161850
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/161850
Therefore, the GCF of Fractions 380/975,136/830 is 4/161850
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 975,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(975,830) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(975,830) x common factors =5 x 1 = 5
LCM(975,830) = ( 975 × 830 ) / 5
LCM(975,830) = 809250 / 5
LCM(975,830) = 161850
