Given numbers are 343, 212, 621, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 212) = 72716
GCD(343, 212) = ( 343 x 212 ) / 72716
= 343 / 212
= 343
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 343, 212, 621, 409 is 1
