Given numbers are 820, 928, 391, 740

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 928 are 2 x 2 x 2 x 2 x 2 x 29

Prime factors of 391 are 17 x 23

Prime factors of 740 are 2 x 2 x 5 x 37

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

Given numbers are 820, 928, 391, 740

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

Apply this formula for all numbers.

Step1:

LCM(820, 928) = 190240

GCD(820, 928) = ( 820 x 928 ) / 190240

= 820 / 928

= 820

Step2:

LCM(4, 391) = 1564

GCD(4, 391) = ( 4 x 391 ) / 1564

= 4 / 391

= 4

Step3:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

So, Greatest Common Divisor of 820, 928, 391, 740 is 1
