The list of prime factors of all numbers are

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 237 are 3 x 79

Prime factors of 380 are 2 x 2 x 5 x 19

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

Given numbers are 784, 644, 237, 380

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

Apply this formula for all numbers.

Step1:

LCM(784, 644) = 18032

GCD(784, 644) = ( 784 x 644 ) / 18032

= 784 / 644

= 784

Step2:

LCM(28, 237) = 6636

GCD(28, 237) = ( 28 x 237 ) / 6636

= 28 / 237

= 28

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 784, 644, 237, 380 is 1
