Given numbers are 800, 642, 450, 181

The list of prime factors of all numbers are

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 642 are 2 x 3 x 107

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

Prime factors of 181 are 181

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

Given numbers are 800, 642, 450, 181

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

Apply this formula for all numbers.

Step1:

LCM(800, 642) = 256800

GCD(800, 642) = ( 800 x 642 ) / 256800

= 800 / 642

= 800

Step2:

LCM(2, 450) = 450

GCD(2, 450) = ( 2 x 450 ) / 450

= 2 / 450

= 2

Step3:

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

= 2 / 181

= 2

So, Greatest Common Divisor of 800, 642, 450, 181 is 1
