Given numbers are 551, 661, 772, 404

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 661 are 661

Prime factors of 772 are 2 x 2 x 193

Prime factors of 404 are 2 x 2 x 101

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

Given numbers are 551, 661, 772, 404

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

Apply this formula for all numbers.

Step1:

LCM(551, 661) = 364211

GCD(551, 661) = ( 551 x 661 ) / 364211

= 551 / 661

= 551

Step2:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

Step3:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

So, Greatest Common Divisor of 551, 661, 772, 404 is 1
