Given numbers are 189, 501, 402, 856

The list of prime factors of all numbers are

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 501 are 3 x 167

Prime factors of 402 are 2 x 3 x 67

Prime factors of 856 are 2 x 2 x 2 x 107

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

Given numbers are 189, 501, 402, 856

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

Apply this formula for all numbers.

Step1:

LCM(189, 501) = 31563

GCD(189, 501) = ( 189 x 501 ) / 31563

= 189 / 501

= 189

Step2:

LCM(3, 402) = 402

GCD(3, 402) = ( 3 x 402 ) / 402

= 3 / 402

= 3

Step3:

LCM(3, 856) = 2568

GCD(3, 856) = ( 3 x 856 ) / 2568

= 3 / 856

= 3

So, Greatest Common Divisor of 189, 501, 402, 856 is 1
