GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 783) = 505818
GCD(646, 783) = ( 646 x 783 ) / 505818
= 646 / 783
= 646
Step2:
LCM(1, 748) = 748
GCD(1, 748) = ( 1 x 748 ) / 748
= 1 / 748
= 1
Step3:
LCM(1, 547) = 547
GCD(1, 547) = ( 1 x 547 ) / 547
= 1 / 547
= 1
So, Greatest Common Divisor of 646, 783, 748, 547 is 1
