Finding GCD of 663, 660, 247 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(663, 660) = 145860
GCD(663, 660) = ( 663 x 660 ) / 145860
GCD(663, 660) = 437580 / 145860
GCD(663, 660) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 247
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 247) = 741
GCD(3, 247) = ( 3 x 247 ) / 741
GCD(3, 247) = 741 / 741
GCD(3, 247) = 1
GCD of 663, 660, 247 is 1
