Given numbers are 691, 147, 392, 173

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

Apply this formula for all numbers.

Step1:

LCM(691, 147) = 101577

GCD(691, 147) = ( 691 x 147 ) / 101577

= 691 / 147

= 691

Step2:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 691, 147, 392, 173 is 1
