Given numbers are 145, 663, 613, 423

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

Apply this formula for all numbers.

Step1:

LCM(145, 663) = 96135

GCD(145, 663) = ( 145 x 663 ) / 96135

= 145 / 663

= 145

Step2:

LCM(1, 613) = 613

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

= 1 / 613

= 1

Step3:

LCM(1, 423) = 423

GCD(1, 423) = ( 1 x 423 ) / 423

= 1 / 423

= 1

So, Greatest Common Divisor of 145, 663, 613, 423 is 1
