Given numbers are 420, 145, 824, 437

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 145 are 5 x 29

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 437 are 19 x 23

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

Given numbers are 420, 145, 824, 437

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

Apply this formula for all numbers.

Step1:

LCM(420, 145) = 12180

GCD(420, 145) = ( 420 x 145 ) / 12180

= 420 / 145

= 420

Step2:

LCM(5, 824) = 4120

GCD(5, 824) = ( 5 x 824 ) / 4120

= 5 / 824

= 5

Step3:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

So, Greatest Common Divisor of 420, 145, 824, 437 is 1
