Given numbers are 981, 142, 758, 256

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

Apply this formula for all numbers.

Step1:

LCM(981, 142) = 139302

GCD(981, 142) = ( 981 x 142 ) / 139302

= 981 / 142

= 981

Step2:

LCM(1, 758) = 758

GCD(1, 758) = ( 1 x 758 ) / 758

= 1 / 758

= 1

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 981, 142, 758, 256 is 1
