Given numbers are 133, 145, 545, 648

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 145 are 5 x 29

Prime factors of 545 are 5 x 109

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 133, 145, 545, 648

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

Apply this formula for all numbers.

Step1:

LCM(133, 145) = 19285

GCD(133, 145) = ( 133 x 145 ) / 19285

= 133 / 145

= 133

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 133, 145, 545, 648 is 1
