Lets's calculate LCM of 860,8638
2 | 860, 8638 |
430, 4319 |
∴ So the LCM of the given numbers is 2 x 430 x 4319 = 3714340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/3714340
Therefore, the GCF of Fractions 5415/860,7779/8638 is 3/3714340
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 860,8638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(860,8638) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(860,8638) x common factors =2 x 1 = 2
LCM(860,8638) = ( 860 × 8638 ) / 2
LCM(860,8638) = 7428680 / 2
LCM(860,8638) = 3714340
