Given numbers are 643, 785, 936, 940

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 785 are 5 x 157

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 643, 785, 936, 940

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

Apply this formula for all numbers.

Step1:

LCM(643, 785) = 504755

GCD(643, 785) = ( 643 x 785 ) / 504755

= 643 / 785

= 643

Step2:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 643, 785, 936, 940 is 1
