Given numbers are 353, 390, 771, 838

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

Apply this formula for all numbers.

Step1:

LCM(353, 390) = 137670

GCD(353, 390) = ( 353 x 390 ) / 137670

= 353 / 390

= 353

Step2:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 353, 390, 771, 838 is 1
