The list of prime factors of all numbers are

Prime factors of 807 are 3 x 269

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 649 are 11 x 59

Prime factors of 542 are 2 x 271

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

Given numbers are 807, 688, 649, 542

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

Apply this formula for all numbers.

Step1:

LCM(807, 688) = 555216

GCD(807, 688) = ( 807 x 688 ) / 555216

= 807 / 688

= 807

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 542) = 542

GCD(1, 542) = ( 1 x 542 ) / 542

= 1 / 542

= 1

So, Greatest Common Divisor of 807, 688, 649, 542 is 1
