Finding GCD of 630, 351, 648, 990 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(630, 351) = 24570

GCD(630, 351) = ( 630 x 351 ) / 24570

GCD(630, 351) = 221130 / 24570

GCD(630, 351) = 9


Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 648

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 648) = 648

GCD(9, 648) = ( 9 x 648 ) / 648

GCD(9, 648) = 5832 / 648

GCD(9, 648) = 9


Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 990

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 990) = 990

GCD(9, 990) = ( 9 x 990 ) / 990

GCD(9, 990) = 8910 / 990

GCD(9, 990) = 9

GCD of 630, 351, 648, 990 is 9
