Given numbers are 838, 320, 619, 397
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 320) = 134080
GCD(838, 320) = ( 838 x 320 ) / 134080
= 838 / 320
= 838
Step2:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
Step3:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
So, Greatest Common Divisor of 838, 320, 619, 397 is 1
