Given numbers are 685, 620, 383, 879

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

Apply this formula for all numbers.

Step1:

LCM(685, 620) = 84940

GCD(685, 620) = ( 685 x 620 ) / 84940

= 685 / 620

= 685

Step2:

LCM(5, 383) = 1915

GCD(5, 383) = ( 5 x 383 ) / 1915

= 5 / 383

= 5

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 685, 620, 383, 879 is 1
