Given numbers are 411, 280, 660, 549

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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 411, 280, 660, 549

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

Apply this formula for all numbers.

Step1:

LCM(411, 280) = 115080

GCD(411, 280) = ( 411 x 280 ) / 115080

= 411 / 280

= 411

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 411, 280, 660, 549 is 1
