Given numbers are 623, 380, 570, 642

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

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

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 623, 380, 570, 642

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

Apply this formula for all numbers.

Step1:

LCM(623, 380) = 236740

GCD(623, 380) = ( 623 x 380 ) / 236740

= 623 / 380

= 623

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 623, 380, 570, 642 is 1
