Given numbers are 172, 785, 390, 833

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

Apply this formula for all numbers.

Step1:

LCM(172, 785) = 135020

GCD(172, 785) = ( 172 x 785 ) / 135020

= 172 / 785

= 172

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

So, Greatest Common Divisor of 172, 785, 390, 833 is 1
