Given numbers are 988, 646, 43, 647

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(988, 646) = 16796

GCD(988, 646) = ( 988 x 646 ) / 16796

= 988 / 646

= 988

Step2:

LCM(38, 43) = 1634

GCD(38, 43) = ( 38 x 43 ) / 1634

= 38 / 43

= 38

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 988, 646, 43, 647 is 1
