Given numbers are 731, 718, 638, 815

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

Apply this formula for all numbers.

Step1:

LCM(731, 718) = 524858

GCD(731, 718) = ( 731 x 718 ) / 524858

= 731 / 718

= 731

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 731, 718, 638, 815 is 1
