Given numbers are 165, 654, 106, 816

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 654 are 2 x 3 x 109

Prime factors of 106 are 2 x 53

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 165, 654, 106, 816

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

Apply this formula for all numbers.

Step1:

LCM(165, 654) = 35970

GCD(165, 654) = ( 165 x 654 ) / 35970

= 165 / 654

= 165

Step2:

LCM(3, 106) = 318

GCD(3, 106) = ( 3 x 106 ) / 318

= 3 / 106

= 3

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 165, 654, 106, 816 is 1
