Given numbers are 402, 440, 785, 866

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 785 are 5 x 157

Prime factors of 866 are 2 x 433

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 402, 440, 785, 866

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

Apply this formula for all numbers.

Step1:

LCM(402, 440) = 88440

GCD(402, 440) = ( 402 x 440 ) / 88440

= 402 / 440

= 402

Step2:

LCM(2, 785) = 1570

GCD(2, 785) = ( 2 x 785 ) / 1570

= 2 / 785

= 2

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 402, 440, 785, 866 is 1
