Given numbers are 665, 543, 681, 684

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 543 are 3 x 181

Prime factors of 681 are 3 x 227

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 665, 543, 681, 684

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

Apply this formula for all numbers.

Step1:

LCM(665, 543) = 361095

GCD(665, 543) = ( 665 x 543 ) / 361095

= 665 / 543

= 665

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 665, 543, 681, 684 is 1
