Given numbers are 398, 322, 289, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 322) = 64078
GCD(398, 322) = ( 398 x 322 ) / 64078
= 398 / 322
= 398
Step2:
LCM(2, 289) = 578
GCD(2, 289) = ( 2 x 289 ) / 578
= 2 / 289
= 2
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 398, 322, 289, 407 is 1
