Given numbers are 455, 865, 812, 199

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

Apply this formula for all numbers.

Step1:

LCM(455, 865) = 78715

GCD(455, 865) = ( 455 x 865 ) / 78715

= 455 / 865

= 455

Step2:

LCM(5, 812) = 4060

GCD(5, 812) = ( 5 x 812 ) / 4060

= 5 / 812

= 5

Step3:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 455, 865, 812, 199 is 1
