Given numbers are 685, 625, 397, 454

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

Apply this formula for all numbers.

Step1:

LCM(685, 625) = 85625

GCD(685, 625) = ( 685 x 625 ) / 85625

= 685 / 625

= 685

Step2:

LCM(5, 397) = 1985

GCD(5, 397) = ( 5 x 397 ) / 1985

= 5 / 397

= 5

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 685, 625, 397, 454 is 1
