Given numbers are 682, 218, 645, 579

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

Apply this formula for all numbers.

Step1:

LCM(682, 218) = 74338

GCD(682, 218) = ( 682 x 218 ) / 74338

= 682 / 218

= 682

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 682, 218, 645, 579 is 1
