Given numbers are 143, 551, 109, 648

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 551 are 19 x 29

Prime factors of 109 are 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 143, 551, 109, 648

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

Apply this formula for all numbers.

Step1:

LCM(143, 551) = 78793

GCD(143, 551) = ( 143 x 551 ) / 78793

= 143 / 551

= 143

Step2:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

Step3:

LCM(1, 648) = 648

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

= 1 / 648

= 1

So, Greatest Common Divisor of 143, 551, 109, 648 is 1
