Given numbers are 190, 605, 643, 838
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(190, 605) = 22990
GCD(190, 605) = ( 190 x 605 ) / 22990
= 190 / 605
= 190
Step2:
LCM(5, 643) = 3215
GCD(5, 643) = ( 5 x 643 ) / 3215
= 5 / 643
= 5
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 190, 605, 643, 838 is 1
