Given numbers are 861, 658, 551, 396

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 658 are 2 x 7 x 47

Prime factors of 551 are 19 x 29

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

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

Given numbers are 861, 658, 551, 396

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

Apply this formula for all numbers.

Step1:

LCM(861, 658) = 80934

GCD(861, 658) = ( 861 x 658 ) / 80934

= 861 / 658

= 861

Step2:

LCM(7, 551) = 3857

GCD(7, 551) = ( 7 x 551 ) / 3857

= 7 / 551

= 7

Step3:

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

= 1 / 396

= 1

So, Greatest Common Divisor of 861, 658, 551, 396 is 1
