Given numbers are 170, 894, 390, 790

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

Apply this formula for all numbers.

Step1:

LCM(170, 894) = 75990

GCD(170, 894) = ( 170 x 894 ) / 75990

= 170 / 894

= 170

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 790) = 790

GCD(2, 790) = ( 2 x 790 ) / 790

= 2 / 790

= 2

So, Greatest Common Divisor of 170, 894, 390, 790 is 2
