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

Apply this formula for all numbers.

Step1:

LCM(897, 299) = 897

GCD(897, 299) = ( 897 x 299 ) / 897

= 897 / 299

= 897

Step2:

LCM(299, 247) = 5681

GCD(299, 247) = ( 299 x 247 ) / 5681

= 299 / 247

= 299

Step3:

LCM(13, 455) = 455

GCD(13, 455) = ( 13 x 455 ) / 455

= 13 / 455

= 13

So, Greatest Common Divisor of 897, 299, 247, 455 is 13
