Now, list down the factors of 7200
:1,2,3,4,5,6,8,9,10,12,15,16,18,20,24,25,30,32,36,40,45,48,50,60,72,75,80,90,96,100,120,144,150,160,180,200,225,240,288,300,360,400,450,480,600,720,800,900,1200,1440,1800,2400,3600,7200
Greatest Common Factor
We found the factors 800,7200 . The biggest common factor number is the GCF number.
So the greatest common factor 800,7200 is 800.
Lets's calculate LCM of 99,610
Given numbers has no common factors except 1. So, there LCM is their product i.e 60390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 800/60390
Therefore, the GCF of Fractions 800/99,7200/610 is 800/60390
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 99,610 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,610) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,610) x common factors =1 x 1 = 1
LCM(99,610) = ( 99 × 610 ) / 1
LCM(99,610) = 60390 / 1
LCM(99,610) = 60390
