Given numbers are 648, 236, 555, 155

The list of prime factors of all numbers are

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

Prime factors of 236 are 2 x 2 x 59

Prime factors of 555 are 3 x 5 x 37

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 648, 236, 555, 155

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

Apply this formula for all numbers.

Step1:

LCM(648, 236) = 38232

GCD(648, 236) = ( 648 x 236 ) / 38232

= 648 / 236

= 648

Step2:

LCM(4, 555) = 2220

GCD(4, 555) = ( 4 x 555 ) / 2220

= 4 / 555

= 4

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 648, 236, 555, 155 is 1
