Lets's calculate GCF of 1,677,794
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 1
:1
Now, list down the factors of 677
:1,677
Now, list down the factors of 794
:1,2,397,794
Greatest Common Factor
We found the factors 1,677,794 . The biggest common factor number is the GCF number.
So the greatest common factor 1,677,794 is 1.
Lets's calculate LCM of 69,79,70
Given numbers has no common factors except 1. So, there LCM is their product i.e 381570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/381570
Therefore, the GCF of Fractions 1/69,677/79,794/70 is 1/381570
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 69,79,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,79,70) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(69,79,70) x common factors =1 x 1 = 1
LCM(69,79,70) = ( 69 × 79 × 70 ) / 1
LCM(69,79,70) = 381570 / 1
LCM(69,79,70) = 381570
