Given numbers are 764, 475, 981, 840

The list of prime factors of all numbers are

Prime factors of 764 are 2 x 2 x 191

Prime factors of 475 are 5 x 5 x 19

Prime factors of 981 are 3 x 3 x 109

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 764, 475, 981, 840

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

Apply this formula for all numbers.

Step1:

LCM(764, 475) = 362900

GCD(764, 475) = ( 764 x 475 ) / 362900

= 764 / 475

= 764

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 764, 475, 981, 840 is 1
