Given numbers are 981, 837, 476, 861

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

Apply this formula for all numbers.

Step1:

LCM(981, 837) = 91233

GCD(981, 837) = ( 981 x 837 ) / 91233

= 981 / 837

= 981

Step2:

LCM(9, 476) = 4284

GCD(9, 476) = ( 9 x 476 ) / 4284

= 9 / 476

= 9

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 981, 837, 476, 861 is 1
