Given numbers are 981, 621, 156, 461

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

Apply this formula for all numbers.

Step1:

LCM(981, 621) = 67689

GCD(981, 621) = ( 981 x 621 ) / 67689

= 981 / 621

= 981

Step2:

LCM(9, 156) = 468

GCD(9, 156) = ( 9 x 156 ) / 468

= 9 / 156

= 9

Step3:

LCM(3, 461) = 1383

GCD(3, 461) = ( 3 x 461 ) / 1383

= 3 / 461

= 3

So, Greatest Common Divisor of 981, 621, 156, 461 is 1
