Given numbers are 454, 289, 85

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

Apply this formula for all numbers.

Step1:

LCM(454, 289) = 131206

GCD(454, 289) = ( 454 x 289 ) / 131206

= 454 / 289

= 454

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

So, Greatest Common Divisor of 454, 289, 85 is 1
