:1,2,7,14,61,122,427,854
Greatest Common Factor
We found the factors 820,854 . The biggest common factor number is the GCF number.
So the greatest common factor 820,854 is 2.
Lets's calculate LCM of 860,412
2 | 860, 412 |
2 | 430, 206 |
215, 103 |
∴ So the LCM of the given numbers is 2 x 2 x 215 x 103 = 88580
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/88580
Therefore, the GCF of Fractions 820/860,854/412 is 2/88580
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 860,412 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(860,412) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(860,412) x common factors =4 x 1 = 4
LCM(860,412) = ( 860 × 412 ) / 4
LCM(860,412) = 354320 / 4
LCM(860,412) = 88580
