Given numbers are 549, 672, 564, 155

The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 155 are 5 x 31

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

Given numbers are 549, 672, 564, 155

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

Apply this formula for all numbers.

Step1:

LCM(549, 672) = 122976

GCD(549, 672) = ( 549 x 672 ) / 122976

= 549 / 672

= 549

Step2:

LCM(3, 564) = 564

GCD(3, 564) = ( 3 x 564 ) / 564

= 3 / 564

= 3

Step3:

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

= 3 / 155

= 3

So, Greatest Common Divisor of 549, 672, 564, 155 is 1
