The HCF of 621,786 is 3.
Lets's calculate GCF of 621,786
3 | 621, 786 |
207, 262 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 621
:1,3,9,23,27,69,207,621
Now, list down the factors of 786
:1,2,3,6,131,262,393,786
Greatest Common Factor
We found the factors 621,786 . The biggest common factor number is the GCF number.
So the greatest common factor 621,786 is 3.
Lets's calculate LCM of 51,293
Given numbers has no common factors except 1. So, there LCM is their product i.e 14943
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/14943
Therefore, the GCF of Fractions 621/51,786/293 is 3/14943
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 51,293 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,293) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(51,293) x common factors =1 x 1 = 1
LCM(51,293) = ( 51 × 293 ) / 1
LCM(51,293) = 14943 / 1
LCM(51,293) = 14943
