Given numbers are 723, 133, 781, 840

The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

Prime factors of 133 are 7 x 19

Prime factors of 781 are 11 x 71

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 723, 133, 781, 840

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

Apply this formula for all numbers.

Step1:

LCM(723, 133) = 96159

GCD(723, 133) = ( 723 x 133 ) / 96159

= 723 / 133

= 723

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 723, 133, 781, 840 is 1
