Given numbers are 361, 660, 387, 555

The list of prime factors of all numbers are

Prime factors of 361 are 19 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 387 are 3 x 3 x 43

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 361, 660, 387, 555

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

Apply this formula for all numbers.

Step1:

LCM(361, 660) = 238260

GCD(361, 660) = ( 361 x 660 ) / 238260

= 361 / 660

= 361

Step2:

LCM(1, 387) = 387

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

= 1 / 387

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 361, 660, 387, 555 is 1
