Now, list down the factors of 31
:1,31
Now, list down the factors of 45
:1,3,5,9,15,45
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 31,45,830 . The biggest common factor number is the GCF number.
So the greatest common factor 31,45,830 is 1.
Lets's calculate LCM of 67,601,705
Given numbers has no common factors except 1. So, there LCM is their product i.e 28388235
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/28388235
Therefore, the GCF of Fractions 31/67,45/601,830/705 is 1/28388235
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 67,601,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,601,705) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,601,705) x common factors =1 x 1 = 1
LCM(67,601,705) = ( 67 × 601 × 705 ) / 1
LCM(67,601,705) = 28388235 / 1
LCM(67,601,705) = 28388235
