Given numbers are 687, 153, 826, 823

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

Apply this formula for all numbers.

Step1:

LCM(687, 153) = 35037

GCD(687, 153) = ( 687 x 153 ) / 35037

= 687 / 153

= 687

Step2:

LCM(3, 826) = 2478

GCD(3, 826) = ( 3 x 826 ) / 2478

= 3 / 826

= 3

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 687, 153, 826, 823 is 1
