Given numbers are 145, 921, 768, 516

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 921 are 3 x 307

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 516 are 2 x 2 x 3 x 43

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

Given numbers are 145, 921, 768, 516

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

Apply this formula for all numbers.

Step1:

LCM(145, 921) = 133545

GCD(145, 921) = ( 145 x 921 ) / 133545

= 145 / 921

= 145

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

So, Greatest Common Divisor of 145, 921, 768, 516 is 1
