So the greatest common factor 660,1880 is 20.
Lets's calculate LCM of 830,762
2 | 830, 762 |
415, 381 |
∴ So the LCM of the given numbers is 2 x 415 x 381 = 316230
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/316230
Therefore, the GCF of Fractions 660/830,1880/762 is 20/316230
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 830,762 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(830,762) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(830,762) x common factors =2 x 1 = 2
LCM(830,762) = ( 830 × 762 ) / 2
LCM(830,762) = 632460 / 2
LCM(830,762) = 316230
