Given numbers are 981, 567, 397, 890

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

Apply this formula for all numbers.

Step1:

LCM(981, 567) = 61803

GCD(981, 567) = ( 981 x 567 ) / 61803

= 981 / 567

= 981

Step2:

LCM(9, 397) = 3573

GCD(9, 397) = ( 9 x 397 ) / 3573

= 9 / 397

= 9

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 981, 567, 397, 890 is 1
