Given numbers are 438, 973, 155, 450

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 973 are 7 x 139

Prime factors of 155 are 5 x 31

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

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

Given numbers are 438, 973, 155, 450

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

Apply this formula for all numbers.

Step1:

LCM(438, 973) = 426174

GCD(438, 973) = ( 438 x 973 ) / 426174

= 438 / 973

= 438

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

So, Greatest Common Divisor of 438, 973, 155, 450 is 1
