Given numbers are 838, 144, 515, 769

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

Apply this formula for all numbers.

Step1:

LCM(838, 144) = 60336

GCD(838, 144) = ( 838 x 144 ) / 60336

= 838 / 144

= 838

Step2:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 838, 144, 515, 769 is 1
