Given numbers are 392, 157, 185, 687

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

Apply this formula for all numbers.

Step1:

LCM(392, 157) = 61544

GCD(392, 157) = ( 392 x 157 ) / 61544

= 392 / 157

= 392

Step2:

LCM(1, 185) = 185

GCD(1, 185) = ( 1 x 185 ) / 185

= 1 / 185

= 1

Step3:

LCM(1, 687) = 687

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

= 1 / 687

= 1

So, Greatest Common Divisor of 392, 157, 185, 687 is 1
