Given numbers are 280, 735, 400, 549

The list of prime factors of all numbers are

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

Prime factors of 735 are 3 x 5 x 7 x 7

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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 280, 735, 400, 549

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

Apply this formula for all numbers.

Step1:

LCM(280, 735) = 5880

GCD(280, 735) = ( 280 x 735 ) / 5880

= 280 / 735

= 280

Step2:

LCM(35, 400) = 2800

GCD(35, 400) = ( 35 x 400 ) / 2800

= 35 / 400

= 35

Step3:

LCM(5, 549) = 2745

GCD(5, 549) = ( 5 x 549 ) / 2745

= 5 / 549

= 5

So, Greatest Common Divisor of 280, 735, 400, 549 is 1
