Given numbers are 623, 285, 613, 655

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

Apply this formula for all numbers.

Step1:

LCM(623, 285) = 177555

GCD(623, 285) = ( 623 x 285 ) / 177555

= 623 / 285

= 623

Step2:

LCM(1, 613) = 613

GCD(1, 613) = ( 1 x 613 ) / 613

= 1 / 613

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 623, 285, 613, 655 is 1
