Given numbers are 689, 620, 888, 516

The list of prime factors of all numbers are

Prime factors of 689 are 13 x 53

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 888 are 2 x 2 x 2 x 3 x 37

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 689, 620, 888, 516

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

Apply this formula for all numbers.

Step1:

LCM(689, 620) = 427180

GCD(689, 620) = ( 689 x 620 ) / 427180

= 689 / 620

= 689

Step2:

LCM(1, 888) = 888

GCD(1, 888) = ( 1 x 888 ) / 888

= 1 / 888

= 1

Step3:

LCM(1, 516) = 516

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

= 1 / 516

= 1

So, Greatest Common Divisor of 689, 620, 888, 516 is 1
