Given numbers are 838, 289, 280

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

Apply this formula for all numbers.

Step1:

LCM(838, 289) = 242182

GCD(838, 289) = ( 838 x 289 ) / 242182

= 838 / 289

= 838

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 838, 289, 280 is 1
