Given numbers are 740, 831, 455, 815

The list of prime factors of all numbers are

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 831 are 3 x 277

Prime factors of 455 are 5 x 7 x 13

Prime factors of 815 are 5 x 163

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

Given numbers are 740, 831, 455, 815

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

Apply this formula for all numbers.

Step1:

LCM(740, 831) = 614940

GCD(740, 831) = ( 740 x 831 ) / 614940

= 740 / 831

= 740

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 740, 831, 455, 815 is 1
