Given numbers are 543, 251, 842, 660

The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 251 are 251

Prime factors of 842 are 2 x 421

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

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

Given numbers are 543, 251, 842, 660

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

Apply this formula for all numbers.

Step1:

LCM(543, 251) = 136293

GCD(543, 251) = ( 543 x 251 ) / 136293

= 543 / 251

= 543

Step2:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 543, 251, 842, 660 is 1
