Given numbers are 455, 688, 803, 202

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 803 are 11 x 73

Prime factors of 202 are 2 x 101

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

Given numbers are 455, 688, 803, 202

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

Apply this formula for all numbers.

Step1:

LCM(455, 688) = 313040

GCD(455, 688) = ( 455 x 688 ) / 313040

= 455 / 688

= 455

Step2:

LCM(1, 803) = 803

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

= 1 / 803

= 1

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 455, 688, 803, 202 is 1
