Given numbers are 862, 138, 768, 921

The list of prime factors of all numbers are

Prime factors of 862 are 2 x 431

Prime factors of 138 are 2 x 3 x 23

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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 862, 138, 768, 921

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

Apply this formula for all numbers.

Step1:

LCM(862, 138) = 59478

GCD(862, 138) = ( 862 x 138 ) / 59478

= 862 / 138

= 862

Step2:

LCM(2, 768) = 768

GCD(2, 768) = ( 2 x 768 ) / 768

= 2 / 768

= 2

Step3:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

So, Greatest Common Divisor of 862, 138, 768, 921 is 1
