Given numbers are 454, 205, 773, 638

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

Apply this formula for all numbers.

Step1:

LCM(454, 205) = 93070

GCD(454, 205) = ( 454 x 205 ) / 93070

= 454 / 205

= 454

Step2:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 454, 205, 773, 638 is 1
