Given numbers are 225, 247, 865, 812

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

Apply this formula for all numbers.

Step1:

LCM(225, 247) = 55575

GCD(225, 247) = ( 225 x 247 ) / 55575

= 225 / 247

= 225

Step2:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 225, 247, 865, 812 is 1
