Given numbers are 430, 388, 838, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 388) = 83420
GCD(430, 388) = ( 430 x 388 ) / 83420
= 430 / 388
= 430
Step2:
LCM(2, 838) = 838
GCD(2, 838) = ( 2 x 838 ) / 838
= 2 / 838
= 2
Step3:
LCM(2, 397) = 794
GCD(2, 397) = ( 2 x 397 ) / 794
= 2 / 397
= 2
So, Greatest Common Divisor of 430, 388, 838, 397 is 1
