Given numbers are 685, 830, 136, 292

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

Apply this formula for all numbers.

Step1:

LCM(685, 830) = 113710

GCD(685, 830) = ( 685 x 830 ) / 113710

= 685 / 830

= 685

Step2:

LCM(5, 136) = 680

GCD(5, 136) = ( 5 x 136 ) / 680

= 5 / 136

= 5

Step3:

LCM(1, 292) = 292

GCD(1, 292) = ( 1 x 292 ) / 292

= 1 / 292

= 1

So, Greatest Common Divisor of 685, 830, 136, 292 is 1
