Given numbers are 542, 780, 666, 755

The list of prime factors of all numbers are

Prime factors of 542 are 2 x 271

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

Prime factors of 666 are 2 x 3 x 3 x 37

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 542, 780, 666, 755

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

Apply this formula for all numbers.

Step1:

LCM(542, 780) = 211380

GCD(542, 780) = ( 542 x 780 ) / 211380

= 542 / 780

= 542

Step2:

LCM(2, 666) = 666

GCD(2, 666) = ( 2 x 666 ) / 666

= 2 / 666

= 2

Step3:

LCM(2, 755) = 1510

GCD(2, 755) = ( 2 x 755 ) / 1510

= 2 / 755

= 2

So, Greatest Common Divisor of 542, 780, 666, 755 is 1
