Given numbers are 623, 312, 784, 158

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

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

Prime factors of 158 are 2 x 79

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

Given numbers are 623, 312, 784, 158

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

Apply this formula for all numbers.

Step1:

LCM(623, 312) = 194376

GCD(623, 312) = ( 623 x 312 ) / 194376

= 623 / 312

= 623

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 623, 312, 784, 158 is 1
