Given numbers are 643, 553, 144, 614

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 553 are 7 x 79

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 614 are 2 x 307

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

Given numbers are 643, 553, 144, 614

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

Apply this formula for all numbers.

Step1:

LCM(643, 553) = 355579

GCD(643, 553) = ( 643 x 553 ) / 355579

= 643 / 553

= 643

Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

Step3:

LCM(1, 614) = 614

GCD(1, 614) = ( 1 x 614 ) / 614

= 1 / 614

= 1

So, Greatest Common Divisor of 643, 553, 144, 614 is 1
