GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(754, 972) = 366444
GCD(754, 972) = ( 754 x 972 ) / 366444
= 754 / 972
= 754
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 403) = 806
GCD(2, 403) = ( 2 x 403 ) / 806
= 2 / 403
= 2
So, Greatest Common Divisor of 754, 972, 646, 403 is 1
