Given numbers are 878, 403, 121, 961

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

Apply this formula for all numbers.

Step1:

LCM(878, 403) = 353834

GCD(878, 403) = ( 878 x 403 ) / 353834

= 878 / 403

= 878

Step2:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

Step3:

LCM(1, 961) = 961

GCD(1, 961) = ( 1 x 961 ) / 961

= 1 / 961

= 1

So, Greatest Common Divisor of 878, 403, 121, 961 is 1
