Lets's calculate GCF of 420,759
3 | 420, 759 |
140, 253 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 420
:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Now, list down the factors of 759
:1,3,11,23,33,69,253,759
Greatest Common Factor
We found the factors 420,759 . The biggest common factor number is the GCF number.
So the greatest common factor 420,759 is 3.
Lets's calculate LCM of 37,230
Given numbers has no common factors except 1. So, there LCM is their product i.e 8510
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/8510
Therefore, the GCF of Fractions 420/37,759/230 is 3/8510
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 37,230 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,230) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,230) x common factors =1 x 1 = 1
LCM(37,230) = ( 37 × 230 ) / 1
LCM(37,230) = 8510 / 1
LCM(37,230) = 8510
