Given numbers are 215, 656, 768, 162

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 162 are 2 x 3 x 3 x 3 x 3

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

Given numbers are 215, 656, 768, 162

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

Apply this formula for all numbers.

Step1:

LCM(215, 656) = 141040

GCD(215, 656) = ( 215 x 656 ) / 141040

= 215 / 656

= 215

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 215, 656, 768, 162 is 1
