Given numbers are 785, 345, 421, 887

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

Apply this formula for all numbers.

Step1:

LCM(785, 345) = 54165

GCD(785, 345) = ( 785 x 345 ) / 54165

= 785 / 345

= 785

Step2:

LCM(5, 421) = 2105

GCD(5, 421) = ( 5 x 421 ) / 2105

= 5 / 421

= 5

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 785, 345, 421, 887 is 1
