Given numbers are 905, 121, 56, 225

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

Apply this formula for all numbers.

Step1:

LCM(905, 121) = 109505

GCD(905, 121) = ( 905 x 121 ) / 109505

= 905 / 121

= 905

Step2:

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

= 1 / 56

= 1

Step3:

LCM(1, 225) = 225

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

= 1 / 225

= 1

So, Greatest Common Divisor of 905, 121, 56, 225 is 1
