Given numbers are 155, 153, 225

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

Apply this formula for all numbers.

Step1:

LCM(155, 153) = 23715

GCD(155, 153) = ( 155 x 153 ) / 23715

= 155 / 153

= 155

Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 155, 153, 225 is 1
