So the greatest common factor 78,90,556 is 2.
Lets's calculate LCM of 754,479,780
2 | 754, 479, 780 |
13 | 377, 479, 390 |
29, 479, 30 |
∴ So the LCM of the given numbers is 2 x 13 x 29 x 479 x 30 = 10834980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10834980
Therefore, the GCF of Fractions 78/754,90/479,556/780 is 2/10834980
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 754,479,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(754,479,780) = 1
common factors(in case of two or more numbers have common factors) = 26
GCF(754,479,780) x common factors =1 x 26 = 26
LCM(754,479,780) = ( 754 × 479 × 780 ) / 26
LCM(754,479,780) = 281709480 / 26
LCM(754,479,780) = 10834980
