Given numbers are 619, 864, 643, 555

The list of prime factors of all numbers are

Prime factors of 619 are 619

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 643 are 643

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 619, 864, 643, 555

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

Apply this formula for all numbers.

Step1:

LCM(619, 864) = 534816

GCD(619, 864) = ( 619 x 864 ) / 534816

= 619 / 864

= 619

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 555) = 555

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

= 1 / 555

= 1

So, Greatest Common Divisor of 619, 864, 643, 555 is 1
