Given numbers are 782, 221, 401, 383

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

Apply this formula for all numbers.

Step1:

LCM(782, 221) = 10166

GCD(782, 221) = ( 782 x 221 ) / 10166

= 782 / 221

= 782

Step2:

LCM(17, 401) = 6817

GCD(17, 401) = ( 17 x 401 ) / 6817

= 17 / 401

= 17

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 782, 221, 401, 383 is 1
