Given numbers are 665, 298, 803, 411

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 298 are 2 x 149

Prime factors of 803 are 11 x 73

Prime factors of 411 are 3 x 137

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

Given numbers are 665, 298, 803, 411

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

Apply this formula for all numbers.

Step1:

LCM(665, 298) = 198170

GCD(665, 298) = ( 665 x 298 ) / 198170

= 665 / 298

= 665

Step2:

LCM(1, 803) = 803

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

= 1 / 803

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 665, 298, 803, 411 is 1
