Given numbers are 818, 455, 651, 765

The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 455 are 5 x 7 x 13

Prime factors of 651 are 3 x 7 x 31

Prime factors of 765 are 3 x 3 x 5 x 17

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

Given numbers are 818, 455, 651, 765

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

Apply this formula for all numbers.

Step1:

LCM(818, 455) = 372190

GCD(818, 455) = ( 818 x 455 ) / 372190

= 818 / 455

= 818

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

= 1 / 765

= 1

So, Greatest Common Divisor of 818, 455, 651, 765 is 1
