Given numbers are 158, 890, 403, 397

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

Apply this formula for all numbers.

Step1:

LCM(158, 890) = 70310

GCD(158, 890) = ( 158 x 890 ) / 70310

= 158 / 890

= 158

Step2:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 158, 890, 403, 397 is 1
