Lets's calculate GCF of 660,155
5 | 660, 155 |
132, 31 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 660
:1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660
Now, list down the factors of 155
:1,5,31,155
Greatest Common Factor
We found the factors 660,155 . The biggest common factor number is the GCF number.
So the greatest common factor 660,155 is 5.
Lets's calculate LCM of 97,875
Given numbers has no common factors except 1. So, there LCM is their product i.e 84875
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/84875
Therefore, the GCF of Fractions 660/97,155/875 is 5/84875
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 97,875 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,875) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,875) x common factors =1 x 1 = 1
LCM(97,875) = ( 97 × 875 ) / 1
LCM(97,875) = 84875 / 1
LCM(97,875) = 84875
