Given numbers are 455, 435, 771, 903

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

Apply this formula for all numbers.

Step1:

LCM(455, 435) = 39585

GCD(455, 435) = ( 455 x 435 ) / 39585

= 455 / 435

= 455

Step2:

LCM(5, 771) = 3855

GCD(5, 771) = ( 5 x 771 ) / 3855

= 5 / 771

= 5

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 455, 435, 771, 903 is 1
