Lets's calculate LCM of 360,840
2 | 360, 840 |
2 | 180, 420 |
2 | 90, 210 |
3 | 45, 105 |
5 | 15, 35 |
3, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 3 x 7 = 2520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/2520
Therefore, the GCF of Fractions 508/360,836/840 is 4/2520
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 360,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(360,840) = 120
common factors(in case of two or more numbers have common factors) = 1
GCF(360,840) x common factors =120 x 1 = 120
LCM(360,840) = ( 360 × 840 ) / 120
LCM(360,840) = 302400 / 120
LCM(360,840) = 2520
