Given numbers are 158, 193, 491, 581

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

Apply this formula for all numbers.

Step1:

LCM(158, 193) = 30494

GCD(158, 193) = ( 158 x 193 ) / 30494

= 158 / 193

= 158

Step2:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

Step3:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

So, Greatest Common Divisor of 158, 193, 491, 581 is 1
