Given numbers are 440, 305, 349, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 305) = 26840
GCD(440, 305) = ( 440 x 305 ) / 26840
= 440 / 305
= 440
Step2:
LCM(5, 349) = 1745
GCD(5, 349) = ( 5 x 349 ) / 1745
= 5 / 349
= 5
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 440, 305, 349, 306 is 1
