Given numbers are 840, 828, 685, 773

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 685 are 5 x 137

Prime factors of 773 are 773

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

Given numbers are 840, 828, 685, 773

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

Apply this formula for all numbers.

Step1:

LCM(840, 828) = 57960

GCD(840, 828) = ( 840 x 828 ) / 57960

= 840 / 828

= 840

Step2:

LCM(12, 685) = 8220

GCD(12, 685) = ( 12 x 685 ) / 8220

= 12 / 685

= 12

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 840, 828, 685, 773 is 1
