Given numbers are 178, 351, 155, 685

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

Apply this formula for all numbers.

Step1:

LCM(178, 351) = 62478

GCD(178, 351) = ( 178 x 351 ) / 62478

= 178 / 351

= 178

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 178, 351, 155, 685 is 1
