Given numbers are 551, 144, 690, 603

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

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

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 603 are 3 x 3 x 67

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

Given numbers are 551, 144, 690, 603

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

Apply this formula for all numbers.

Step1:

LCM(551, 144) = 79344

GCD(551, 144) = ( 551 x 144 ) / 79344

= 551 / 144

= 551

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 551, 144, 690, 603 is 1
