The factors of 25 are 1, 5, 25
The factors of 55 are 1, 5, 11, 55
The factors of 136 are 1, 2, 4, 8, 17, 34, 68, 136
The HCF of 25,55,136 is 1.
Lets's calculate GCF of 25,55,136
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 25
:1,5,25
Now, list down the factors of 55
:1,5,11,55
Now, list down the factors of 136
:1,2,4,8,17,34,68,136
Greatest Common Factor
We found the factors 25,55,136 . The biggest common factor number is the GCF number.
So the greatest common factor 25,55,136 is 1.
Lets's calculate LCM of 26,81,61
Given numbers has no common factors except 1. So, there LCM is their product i.e 128466
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/128466
Therefore, the GCF of Fractions 25/26,55/81,136/61 is 1/128466
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 26,81,61 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,81,61) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(26,81,61) x common factors =1 x 1 = 1
LCM(26,81,61) = ( 26 × 81 × 61 ) / 1
LCM(26,81,61) = 128466 / 1
LCM(26,81,61) = 128466
