Given numbers are 988, 640, 128, 783

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

Apply this formula for all numbers.

Step1:

LCM(988, 640) = 158080

GCD(988, 640) = ( 988 x 640 ) / 158080

= 988 / 640

= 988

Step2:

LCM(4, 128) = 128

GCD(4, 128) = ( 4 x 128 ) / 128

= 4 / 128

= 4

Step3:

LCM(4, 783) = 3132

GCD(4, 783) = ( 4 x 783 ) / 3132

= 4 / 783

= 4

So, Greatest Common Divisor of 988, 640, 128, 783 is 1
