Given numbers are 940, 920, 168, 921

The list of prime factors of all numbers are

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

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 940, 920, 168, 921

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

Apply this formula for all numbers.

Step1:

LCM(940, 920) = 43240

GCD(940, 920) = ( 940 x 920 ) / 43240

= 940 / 920

= 940

Step2:

LCM(20, 168) = 840

GCD(20, 168) = ( 20 x 168 ) / 840

= 20 / 168

= 20

Step3:

LCM(4, 921) = 3684

GCD(4, 921) = ( 4 x 921 ) / 3684

= 4 / 921

= 4

So, Greatest Common Divisor of 940, 920, 168, 921 is 1
