Given numbers are 160, 397, 687, 811

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

Apply this formula for all numbers.

Step1:

LCM(160, 397) = 63520

GCD(160, 397) = ( 160 x 397 ) / 63520

= 160 / 397

= 160

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 160, 397, 687, 811 is 1
