GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(756, 657) = 55188
GCD(756, 657) = ( 756 x 657 ) / 55188
= 756 / 657
= 756
Step2:
LCM(9, 204) = 612
GCD(9, 204) = ( 9 x 204 ) / 612
= 9 / 204
= 9
Step3:
LCM(3, 434) = 1302
GCD(3, 434) = ( 3 x 434 ) / 1302
= 3 / 434
= 3
So, Greatest Common Divisor of 756, 657, 204, 434 is 1
