Given numbers are 420, 545, 809, 150

The list of prime factors of all numbers are

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

Prime factors of 545 are 5 x 109

Prime factors of 809 are 809

Prime factors of 150 are 2 x 3 x 5 x 5

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

Given numbers are 420, 545, 809, 150

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

Apply this formula for all numbers.

Step1:

LCM(420, 545) = 45780

GCD(420, 545) = ( 420 x 545 ) / 45780

= 420 / 545

= 420

Step2:

LCM(5, 809) = 4045

GCD(5, 809) = ( 5 x 809 ) / 4045

= 5 / 809

= 5

Step3:

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

= 1 / 150

= 1

So, Greatest Common Divisor of 420, 545, 809, 150 is 1
