Given numbers are 610, 788, 451, 390

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

Prime factors of 788 are 2 x 2 x 197

Prime factors of 451 are 11 x 41

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 610, 788, 451, 390

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

Apply this formula for all numbers.

Step1:

LCM(610, 788) = 240340

GCD(610, 788) = ( 610 x 788 ) / 240340

= 610 / 788

= 610

Step2:

LCM(2, 451) = 902

GCD(2, 451) = ( 2 x 451 ) / 902

= 2 / 451

= 2

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 610, 788, 451, 390 is 1
