Given numbers are 787, 145, 866, 320

The list of prime factors of all numbers are

Prime factors of 787 are 787

Prime factors of 145 are 5 x 29

Prime factors of 866 are 2 x 433

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 787, 145, 866, 320

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

Apply this formula for all numbers.

Step1:

LCM(787, 145) = 114115

GCD(787, 145) = ( 787 x 145 ) / 114115

= 787 / 145

= 787

Step2:

LCM(1, 866) = 866

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

= 1 / 866

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 787, 145, 866, 320 is 1
