Given numbers are 365, 420, 678, 287

The list of prime factors of all numbers are

Prime factors of 365 are 5 x 73

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 678 are 2 x 3 x 113

Prime factors of 287 are 7 x 41

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

Given numbers are 365, 420, 678, 287

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

Apply this formula for all numbers.

Step1:

LCM(365, 420) = 30660

GCD(365, 420) = ( 365 x 420 ) / 30660

= 365 / 420

= 365

Step2:

LCM(5, 678) = 3390

GCD(5, 678) = ( 5 x 678 ) / 3390

= 5 / 678

= 5

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 365, 420, 678, 287 is 1
