Given numbers are 685, 822, 215, 587

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

Apply this formula for all numbers.

Step1:

LCM(685, 822) = 4110

GCD(685, 822) = ( 685 x 822 ) / 4110

= 685 / 822

= 685

Step2:

LCM(137, 215) = 29455

GCD(137, 215) = ( 137 x 215 ) / 29455

= 137 / 215

= 137

Step3:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

So, Greatest Common Divisor of 685, 822, 215, 587 is 1
