Given numbers are 690, 858, 823, 135

The list of prime factors of all numbers are

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

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 823 are 823

Prime factors of 135 are 3 x 3 x 3 x 5

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

Given numbers are 690, 858, 823, 135

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

Apply this formula for all numbers.

Step1:

LCM(690, 858) = 98670

GCD(690, 858) = ( 690 x 858 ) / 98670

= 690 / 858

= 690

Step2:

LCM(6, 823) = 4938

GCD(6, 823) = ( 6 x 823 ) / 4938

= 6 / 823

= 6

Step3:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

So, Greatest Common Divisor of 690, 858, 823, 135 is 1
