Given numbers are 703, 351, 789, 840

The list of prime factors of all numbers are

Prime factors of 703 are 19 x 37

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 789 are 3 x 263

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

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

Given numbers are 703, 351, 789, 840

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

Apply this formula for all numbers.

Step1:

LCM(703, 351) = 246753

GCD(703, 351) = ( 703 x 351 ) / 246753

= 703 / 351

= 703

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 703, 351, 789, 840 is 1
