Given numbers are 550, 609, 723, 661

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 609 are 3 x 7 x 29

Prime factors of 723 are 3 x 241

Prime factors of 661 are 661

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

Given numbers are 550, 609, 723, 661

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

Apply this formula for all numbers.

Step1:

LCM(550, 609) = 334950

GCD(550, 609) = ( 550 x 609 ) / 334950

= 550 / 609

= 550

Step2:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 550, 609, 723, 661 is 1
