Given numbers are 921, 954, 455, 207

The list of prime factors of all numbers are

Prime factors of 921 are 3 x 307

Prime factors of 954 are 2 x 3 x 3 x 53

Prime factors of 455 are 5 x 7 x 13

Prime factors of 207 are 3 x 3 x 23

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

Given numbers are 921, 954, 455, 207

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

Apply this formula for all numbers.

Step1:

LCM(921, 954) = 292878

GCD(921, 954) = ( 921 x 954 ) / 292878

= 921 / 954

= 921

Step2:

LCM(3, 455) = 1365

GCD(3, 455) = ( 3 x 455 ) / 1365

= 3 / 455

= 3

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 921, 954, 455, 207 is 1
