Given numbers are 617, 428, 987, 383

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

Apply this formula for all numbers.

Step1:

LCM(617, 428) = 264076

GCD(617, 428) = ( 617 x 428 ) / 264076

= 617 / 428

= 617

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 617, 428, 987, 383 is 1
