Given numbers are 155, 738, 743, 205

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

Apply this formula for all numbers.

Step1:

LCM(155, 738) = 114390

GCD(155, 738) = ( 155 x 738 ) / 114390

= 155 / 738

= 155

Step2:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 155, 738, 743, 205 is 1
