Given numbers are 343, 308, 905, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 308) = 15092
GCD(343, 308) = ( 343 x 308 ) / 15092
= 343 / 308
= 343
Step2:
LCM(7, 905) = 6335
GCD(7, 905) = ( 7 x 905 ) / 6335
= 7 / 905
= 7
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 343, 308, 905, 515 is 1
