Given numbers are 637, 689, 345, 829

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

Apply this formula for all numbers.

Step1:

LCM(637, 689) = 33761

GCD(637, 689) = ( 637 x 689 ) / 33761

= 637 / 689

= 637

Step2:

LCM(13, 345) = 4485

GCD(13, 345) = ( 13 x 345 ) / 4485

= 13 / 345

= 13

Step3:

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

= 1 / 829

= 1

So, Greatest Common Divisor of 637, 689, 345, 829 is 1
