GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 206) = 40376
GCD(392, 206) = ( 392 x 206 ) / 40376
= 392 / 206
= 392
Step2:
LCM(2, 288) = 288
GCD(2, 288) = ( 2 x 288 ) / 288
= 2 / 288
= 2
Step3:
LCM(2, 630) = 630
GCD(2, 630) = ( 2 x 630 ) / 630
= 2 / 630
= 2
So, Greatest Common Divisor of 392, 206, 288, 630 is 2
