Given numbers are 731, 665, 886, 390

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

Apply this formula for all numbers.

Step1:

LCM(731, 665) = 486115

GCD(731, 665) = ( 731 x 665 ) / 486115

= 731 / 665

= 731

Step2:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 731, 665, 886, 390 is 1
