Given numbers are 915, 891, 539, 407

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

Apply this formula for all numbers.

Step1:

LCM(915, 891) = 271755

GCD(915, 891) = ( 915 x 891 ) / 271755

= 915 / 891

= 915

Step2:

LCM(3, 539) = 1617

GCD(3, 539) = ( 3 x 539 ) / 1617

= 3 / 539

= 3

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 915, 891, 539, 407 is 1
