The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 365 are 5 x 73

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 815, 365, 666, 387

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

Apply this formula for all numbers.

Step1:

LCM(815, 365) = 59495

GCD(815, 365) = ( 815 x 365 ) / 59495

= 815 / 365

= 815

Step2:

LCM(5, 666) = 3330

GCD(5, 666) = ( 5 x 666 ) / 3330

= 5 / 666

= 5

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 815, 365, 666, 387 is 1
