Given numbers are 603, 657, 145, 505

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

Apply this formula for all numbers.

Step1:

LCM(603, 657) = 44019

GCD(603, 657) = ( 603 x 657 ) / 44019

= 603 / 657

= 603

Step2:

LCM(9, 145) = 1305

GCD(9, 145) = ( 9 x 145 ) / 1305

= 9 / 145

= 9

Step3:

LCM(1, 505) = 505

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

= 1 / 505

= 1

So, Greatest Common Divisor of 603, 657, 145, 505 is 1
