The HCF of 624,620 is 4.
Lets's calculate GCF of 624,620
2 | 624, 620 |
2 | 312, 310 |
156, 155 |
∴ So the GCF of the given numbers is 2 x 2 = 4
Now, list down the factors of 624
:1,2,3,4,6,8,12,13,16,24,26,39,48,52,78,104,156,208,312,624
Now, list down the factors of 620
:1,2,4,5,10,20,31,62,124,155,310,620
Greatest Common Factor
We found the factors 624,620 . The biggest common factor number is the GCF number.
So the greatest common factor 624,620 is 4.
Lets's calculate LCM of 83,721
Given numbers has no common factors except 1. So, there LCM is their product i.e 59843
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/59843
Therefore, the GCF of Fractions 624/83,620/721 is 4/59843
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 83,721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,721) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(83,721) x common factors =1 x 1 = 1
LCM(83,721) = ( 83 × 721 ) / 1
LCM(83,721) = 59843 / 1
LCM(83,721) = 59843
