Given numbers are 981, 426, 921, 515

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

Apply this formula for all numbers.

Step1:

LCM(981, 426) = 139302

GCD(981, 426) = ( 981 x 426 ) / 139302

= 981 / 426

= 981

Step2:

LCM(3, 921) = 921

GCD(3, 921) = ( 3 x 921 ) / 921

= 3 / 921

= 3

Step3:

LCM(3, 515) = 1545

GCD(3, 515) = ( 3 x 515 ) / 1545

= 3 / 515

= 3

So, Greatest Common Divisor of 981, 426, 921, 515 is 1
