Given numbers are 690, 528, 565, 815

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 565 are 5 x 113

Prime factors of 815 are 5 x 163

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

Given numbers are 690, 528, 565, 815

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

Apply this formula for all numbers.

Step1:

LCM(690, 528) = 60720

GCD(690, 528) = ( 690 x 528 ) / 60720

= 690 / 528

= 690

Step2:

LCM(6, 565) = 3390

GCD(6, 565) = ( 6 x 565 ) / 3390

= 6 / 565

= 6

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 690, 528, 565, 815 is 1
