Given numbers are 908, 686, 698, 621

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

Apply this formula for all numbers.

Step1:

LCM(908, 686) = 311444

GCD(908, 686) = ( 908 x 686 ) / 311444

= 908 / 686

= 908

Step2:

LCM(2, 698) = 698

GCD(2, 698) = ( 2 x 698 ) / 698

= 2 / 698

= 2

Step3:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

So, Greatest Common Divisor of 908, 686, 698, 621 is 1
