Given numbers are 637, 432, 803, 217

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 803 are 11 x 73

Prime factors of 217 are 7 x 31

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

Given numbers are 637, 432, 803, 217

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

Apply this formula for all numbers.

Step1:

LCM(637, 432) = 275184

GCD(637, 432) = ( 637 x 432 ) / 275184

= 637 / 432

= 637

Step2:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 637, 432, 803, 217 is 1
