The list of prime factors of all numbers are

Prime factors of 697 are 17 x 41

Prime factors of 786 are 2 x 3 x 131

Prime factors of 556 are 2 x 2 x 139

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 697, 786, 556, 840

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

Apply this formula for all numbers.

Step1:

LCM(697, 786) = 547842

GCD(697, 786) = ( 697 x 786 ) / 547842

= 697 / 786

= 697

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 697, 786, 556, 840 is 1
