Given numbers are 123, 391, 607, 505

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

Apply this formula for all numbers.

Step1:

LCM(123, 391) = 48093

GCD(123, 391) = ( 123 x 391 ) / 48093

= 123 / 391

= 123

Step2:

LCM(1, 607) = 607

GCD(1, 607) = ( 1 x 607 ) / 607

= 1 / 607

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 123, 391, 607, 505 is 1
