Given numbers are 838, 257, 670, 328

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

Apply this formula for all numbers.

Step1:

LCM(838, 257) = 215366

GCD(838, 257) = ( 838 x 257 ) / 215366

= 838 / 257

= 838

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

Step3:

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

= 1 / 328

= 1

So, Greatest Common Divisor of 838, 257, 670, 328 is 1
