Given numbers are 551, 354, 843, 980

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 354 are 2 x 3 x 59

Prime factors of 843 are 3 x 281

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 551, 354, 843, 980

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

Apply this formula for all numbers.

Step1:

LCM(551, 354) = 195054

GCD(551, 354) = ( 551 x 354 ) / 195054

= 551 / 354

= 551

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 551, 354, 843, 980 is 1
