Given numbers are 392, 385, 756, 170

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

Apply this formula for all numbers.

Step1:

LCM(392, 385) = 21560

GCD(392, 385) = ( 392 x 385 ) / 21560

= 392 / 385

= 392

Step2:

LCM(7, 756) = 756

GCD(7, 756) = ( 7 x 756 ) / 756

= 7 / 756

= 7

Step3:

LCM(7, 170) = 1190

GCD(7, 170) = ( 7 x 170 ) / 1190

= 7 / 170

= 7

So, Greatest Common Divisor of 392, 385, 756, 170 is 1
