Given numbers are 505, 245, 450, 803

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 245 are 5 x 7 x 7

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 803 are 11 x 73

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

Given numbers are 505, 245, 450, 803

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

Apply this formula for all numbers.

Step1:

LCM(505, 245) = 24745

GCD(505, 245) = ( 505 x 245 ) / 24745

= 505 / 245

= 505

Step2:

LCM(5, 450) = 450

GCD(5, 450) = ( 5 x 450 ) / 450

= 5 / 450

= 5

Step3:

LCM(5, 803) = 4015

GCD(5, 803) = ( 5 x 803 ) / 4015

= 5 / 803

= 5

So, Greatest Common Divisor of 505, 245, 450, 803 is 1
