Given numbers are 681, 669, 956, 397

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

Apply this formula for all numbers.

Step1:

LCM(681, 669) = 151863

GCD(681, 669) = ( 681 x 669 ) / 151863

= 681 / 669

= 681

Step2:

LCM(3, 956) = 2868

GCD(3, 956) = ( 3 x 956 ) / 2868

= 3 / 956

= 3

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 681, 669, 956, 397 is 1
