Given numbers are 297, 138, 863, 455

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

Apply this formula for all numbers.

Step1:

LCM(297, 138) = 13662

GCD(297, 138) = ( 297 x 138 ) / 13662

= 297 / 138

= 297

Step2:

LCM(3, 863) = 2589

GCD(3, 863) = ( 3 x 863 ) / 2589

= 3 / 863

= 3

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 297, 138, 863, 455 is 1
