Given numbers are 643, 816, 610, 749

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 610 are 2 x 5 x 61

Prime factors of 749 are 7 x 107

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

Given numbers are 643, 816, 610, 749

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

Apply this formula for all numbers.

Step1:

LCM(643, 816) = 524688

GCD(643, 816) = ( 643 x 816 ) / 524688

= 643 / 816

= 643

Step2:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 643, 816, 610, 749 is 1
