Given numbers are 775, 961, 862, 858

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

Apply this formula for all numbers.

Step1:

LCM(775, 961) = 24025

GCD(775, 961) = ( 775 x 961 ) / 24025

= 775 / 961

= 775

Step2:

LCM(31, 862) = 26722

GCD(31, 862) = ( 31 x 862 ) / 26722

= 31 / 862

= 31

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 775, 961, 862, 858 is 1
