Given numbers are 786, 421, 855, 963

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

Apply this formula for all numbers.

Step1:

LCM(786, 421) = 330906

GCD(786, 421) = ( 786 x 421 ) / 330906

= 786 / 421

= 786

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

So, Greatest Common Divisor of 786, 421, 855, 963 is 1
