Given numbers are 545, 643, 720, 775

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 643 are 643

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 775 are 5 x 5 x 31

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

Given numbers are 545, 643, 720, 775

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

Apply this formula for all numbers.

Step1:

LCM(545, 643) = 350435

GCD(545, 643) = ( 545 x 643 ) / 350435

= 545 / 643

= 545

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 545, 643, 720, 775 is 1
