Given numbers are 387, 940, 561, 616

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

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

Prime factors of 561 are 3 x 11 x 17

Prime factors of 616 are 2 x 2 x 2 x 7 x 11

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

Given numbers are 387, 940, 561, 616

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

Apply this formula for all numbers.

Step1:

LCM(387, 940) = 363780

GCD(387, 940) = ( 387 x 940 ) / 363780

= 387 / 940

= 387

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 616) = 616

GCD(1, 616) = ( 1 x 616 ) / 616

= 1 / 616

= 1

So, Greatest Common Divisor of 387, 940, 561, 616 is 1
