Given numbers are 685, 895, 886, 489

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

Apply this formula for all numbers.

Step1:

LCM(685, 895) = 122615

GCD(685, 895) = ( 685 x 895 ) / 122615

= 685 / 895

= 685

Step2:

LCM(5, 886) = 4430

GCD(5, 886) = ( 5 x 886 ) / 4430

= 5 / 886

= 5

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 685, 895, 886, 489 is 1
