Given numbers are 658, 380, 490, 549

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 549 are 3 x 3 x 61

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

Given numbers are 658, 380, 490, 549

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

Apply this formula for all numbers.

Step1:

LCM(658, 380) = 125020

GCD(658, 380) = ( 658 x 380 ) / 125020

= 658 / 380

= 658

Step2:

LCM(2, 490) = 490

GCD(2, 490) = ( 2 x 490 ) / 490

= 2 / 490

= 2

Step3:

LCM(2, 549) = 1098

GCD(2, 549) = ( 2 x 549 ) / 1098

= 2 / 549

= 2

So, Greatest Common Divisor of 658, 380, 490, 549 is 1
