So the greatest common factor 78,24,826 is 2.
Lets's calculate LCM of 72,755,625
5 | 72, 755, 625 |
72, 151, 125 |
∴ So the LCM of the given numbers is 5 x 72 x 151 x 125 = 6795000
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/6795000
Therefore, the GCF of Fractions 78/72,24/755,826/625 is 2/6795000
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 72,755,625 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,755,625) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(72,755,625) x common factors =1 x 5 = 5
LCM(72,755,625) = ( 72 × 755 × 625 ) / 5
LCM(72,755,625) = 33975000 / 5
LCM(72,755,625) = 6795000
