Given numbers are 225, 861, 454, 154

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

Apply this formula for all numbers.

Step1:

LCM(225, 861) = 64575

GCD(225, 861) = ( 225 x 861 ) / 64575

= 225 / 861

= 225

Step2:

LCM(3, 454) = 1362

GCD(3, 454) = ( 3 x 454 ) / 1362

= 3 / 454

= 3

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 225, 861, 454, 154 is 1
