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

Apply this formula for all numbers.

Step1:

LCM(513, 921) = 157491

GCD(513, 921) = ( 513 x 921 ) / 157491

= 513 / 921

= 513

Step2:

LCM(3, 162) = 162

GCD(3, 162) = ( 3 x 162 ) / 162

= 3 / 162

= 3

Step3:

LCM(3, 681) = 681

GCD(3, 681) = ( 3 x 681 ) / 681

= 3 / 681

= 3

So, Greatest Common Divisor of 513, 921, 162, 681 is 3
