Given numbers are 860, 628, 665, 338

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

Apply this formula for all numbers.

Step1:

LCM(860, 628) = 135020

GCD(860, 628) = ( 860 x 628 ) / 135020

= 860 / 628

= 860

Step2:

LCM(4, 665) = 2660

GCD(4, 665) = ( 4 x 665 ) / 2660

= 4 / 665

= 4

Step3:

LCM(1, 338) = 338

GCD(1, 338) = ( 1 x 338 ) / 338

= 1 / 338

= 1

So, Greatest Common Divisor of 860, 628, 665, 338 is 1
