Given numbers are 249, 252, 545, 921

The list of prime factors of all numbers are

Prime factors of 249 are 3 x 83

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 545 are 5 x 109

Prime factors of 921 are 3 x 307

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

Given numbers are 249, 252, 545, 921

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

Apply this formula for all numbers.

Step1:

LCM(249, 252) = 20916

GCD(249, 252) = ( 249 x 252 ) / 20916

= 249 / 252

= 249

Step2:

LCM(3, 545) = 1635

GCD(3, 545) = ( 3 x 545 ) / 1635

= 3 / 545

= 3

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 249, 252, 545, 921 is 1
