Given numbers are 763, 503, 840, 691

The list of prime factors of all numbers are

Prime factors of 763 are 7 x 109

Prime factors of 503 are 503

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

Prime factors of 691 are 691

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

Given numbers are 763, 503, 840, 691

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

Apply this formula for all numbers.

Step1:

LCM(763, 503) = 383789

GCD(763, 503) = ( 763 x 503 ) / 383789

= 763 / 503

= 763

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 763, 503, 840, 691 is 1
