Given numbers are 720, 158, 545, 530

The list of prime factors of all numbers are

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

Prime factors of 158 are 2 x 79

Prime factors of 545 are 5 x 109

Prime factors of 530 are 2 x 5 x 53

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

Given numbers are 720, 158, 545, 530

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

Apply this formula for all numbers.

Step1:

LCM(720, 158) = 56880

GCD(720, 158) = ( 720 x 158 ) / 56880

= 720 / 158

= 720

Step2:

LCM(2, 545) = 1090

GCD(2, 545) = ( 2 x 545 ) / 1090

= 2 / 545

= 2

Step3:

LCM(1, 530) = 530

GCD(1, 530) = ( 1 x 530 ) / 530

= 1 / 530

= 1

So, Greatest Common Divisor of 720, 158, 545, 530 is 1
