Given numbers are 281, 335, 420, 445

The list of prime factors of all numbers are

Prime factors of 281 are 281

Prime factors of 335 are 5 x 67

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 445 are 5 x 89

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

Given numbers are 281, 335, 420, 445

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

Apply this formula for all numbers.

Step1:

LCM(281, 335) = 94135

GCD(281, 335) = ( 281 x 335 ) / 94135

= 281 / 335

= 281

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 281, 335, 420, 445 is 1
