Given numbers are 156, 397, 449, 633

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

Apply this formula for all numbers.

Step1:

LCM(156, 397) = 61932

GCD(156, 397) = ( 156 x 397 ) / 61932

= 156 / 397

= 156

Step2:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

Step3:

LCM(1, 633) = 633

GCD(1, 633) = ( 1 x 633 ) / 633

= 1 / 633

= 1

So, Greatest Common Divisor of 156, 397, 449, 633 is 1
