Given numbers are 784, 790, 380, 203

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 790 are 2 x 5 x 79

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

Prime factors of 203 are 7 x 29

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

Given numbers are 784, 790, 380, 203

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

Apply this formula for all numbers.

Step1:

LCM(784, 790) = 309680

GCD(784, 790) = ( 784 x 790 ) / 309680

= 784 / 790

= 784

Step2:

LCM(2, 380) = 380

GCD(2, 380) = ( 2 x 380 ) / 380

= 2 / 380

= 2

Step3:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

So, Greatest Common Divisor of 784, 790, 380, 203 is 1
