Given numbers are 915, 979, 845, 561

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

Apply this formula for all numbers.

Step1:

LCM(915, 979) = 895785

GCD(915, 979) = ( 915 x 979 ) / 895785

= 915 / 979

= 915

Step2:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 915, 979, 845, 561 is 1
