Given numbers are 543, 187, 780, 755

The list of prime factors of all numbers are

Prime factors of 543 are 3 x 181

Prime factors of 187 are 11 x 17

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 755 are 5 x 151

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

Given numbers are 543, 187, 780, 755

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

Apply this formula for all numbers.

Step1:

LCM(543, 187) = 101541

GCD(543, 187) = ( 543 x 187 ) / 101541

= 543 / 187

= 543

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 543, 187, 780, 755 is 1
