Given numbers are 392, 172, 85, 794

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

Apply this formula for all numbers.

Step1:

LCM(392, 172) = 16856

GCD(392, 172) = ( 392 x 172 ) / 16856

= 392 / 172

= 392

Step2:

LCM(4, 85) = 340

GCD(4, 85) = ( 4 x 85 ) / 340

= 4 / 85

= 4

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 392, 172, 85, 794 is 1
