The HCF of 651,820 is 1.
Lets's calculate GCF of 651,820
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 651
:1,3,7,21,31,93,217,651
Now, list down the factors of 820
:1,2,4,5,10,20,41,82,164,205,410,820
Greatest Common Factor
We found the factors 651,820 . The biggest common factor number is the GCF number.
So the greatest common factor 651,820 is 1.
Lets's calculate LCM of 612,643
Given numbers has no common factors except 1. So, there LCM is their product i.e 393516
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/393516
Therefore, the GCF of Fractions 651/612,820/643 is 1/393516
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 612,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(612,643) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(612,643) x common factors =1 x 1 = 1
LCM(612,643) = ( 612 × 643 ) / 1
LCM(612,643) = 393516 / 1
LCM(612,643) = 393516
