Given numbers are 755, 455, 838

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

Apply this formula for all numbers.

Step1:

LCM(755, 455) = 68705

GCD(755, 455) = ( 755 x 455 ) / 68705

= 755 / 455

= 755

Step2:

LCM(5, 838) = 4190

GCD(5, 838) = ( 5 x 838 ) / 4190

= 5 / 838

= 5

So, Greatest Common Divisor of 755, 455, 838 is 1
