Given numbers are 981, 655, 610, 938

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

Apply this formula for all numbers.

Step1:

LCM(981, 655) = 642555

GCD(981, 655) = ( 981 x 655 ) / 642555

= 981 / 655

= 981

Step2:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

Step3:

LCM(1, 938) = 938

GCD(1, 938) = ( 1 x 938 ) / 938

= 1 / 938

= 1

So, Greatest Common Divisor of 981, 655, 610, 938 is 1
