Given numbers are 815, 665, 524, 551

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 665 are 5 x 7 x 19

Prime factors of 524 are 2 x 2 x 131

Prime factors of 551 are 19 x 29

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

Given numbers are 815, 665, 524, 551

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

Apply this formula for all numbers.

Step1:

LCM(815, 665) = 108395

GCD(815, 665) = ( 815 x 665 ) / 108395

= 815 / 665

= 815

Step2:

LCM(5, 524) = 2620

GCD(5, 524) = ( 5 x 524 ) / 2620

= 5 / 524

= 5

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 815, 665, 524, 551 is 1
