The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 31 are 1, 31
The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66
The HCF of 36,31,66 is 1.
Lets's calculate GCF of 36,31,66
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 36
:1,2,3,4,6,9,12,18,36
Now, list down the factors of 31
:1,31
Now, list down the factors of 66
:1,2,3,6,11,22,33,66
Greatest Common Factor
We found the factors 36,31,66 . The biggest common factor number is the GCF number.
So the greatest common factor 36,31,66 is 1.
Lets's calculate LCM of 61,73,85
Given numbers has no common factors except 1. So, there LCM is their product i.e 378505
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/378505
Therefore, the GCF of Fractions 36/61,31/73,66/85 is 1/378505
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 61,73,85 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,73,85) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,73,85) x common factors =1 x 1 = 1
LCM(61,73,85) = ( 61 × 73 × 85 ) / 1
LCM(61,73,85) = 378505 / 1
LCM(61,73,85) = 378505
