Given numbers are 155, 405, 182, 435

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

Apply this formula for all numbers.

Step1:

LCM(155, 405) = 12555

GCD(155, 405) = ( 155 x 405 ) / 12555

= 155 / 405

= 155

Step2:

LCM(5, 182) = 910

GCD(5, 182) = ( 5 x 182 ) / 910

= 5 / 182

= 5

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 155, 405, 182, 435 is 1
