GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 766) = 152434
GCD(398, 766) = ( 398 x 766 ) / 152434
= 398 / 766
= 398
Step2:
LCM(2, 338) = 338
GCD(2, 338) = ( 2 x 338 ) / 338
= 2 / 338
= 2
Step3:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
So, Greatest Common Divisor of 398, 766, 338, 919 is 1
