Given numbers are 397, 981, 132, 890

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

Apply this formula for all numbers.

Step1:

LCM(397, 981) = 389457

GCD(397, 981) = ( 397 x 981 ) / 389457

= 397 / 981

= 397

Step2:

LCM(1, 132) = 132

GCD(1, 132) = ( 1 x 132 ) / 132

= 1 / 132

= 1

Step3:

LCM(1, 890) = 890

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

= 1 / 890

= 1

So, Greatest Common Divisor of 397, 981, 132, 890 is 1
