Given numbers are 961, 406, 876, 815

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

Apply this formula for all numbers.

Step1:

LCM(961, 406) = 390166

GCD(961, 406) = ( 961 x 406 ) / 390166

= 961 / 406

= 961

Step2:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 961, 406, 876, 815 is 1
