Given numbers are 455, 112, 634, 821

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 112 are 2 x 2 x 2 x 2 x 7

Prime factors of 634 are 2 x 317

Prime factors of 821 are 821

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 455, 112, 634, 821

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

Apply this formula for all numbers.

Step1:

LCM(455, 112) = 7280

GCD(455, 112) = ( 455 x 112 ) / 7280

= 455 / 112

= 455

Step2:

LCM(7, 634) = 4438

GCD(7, 634) = ( 7 x 634 ) / 4438

= 7 / 634

= 7

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 455, 112, 634, 821 is 1
