Given numbers are 338, 247, 664, 306
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(338, 247) = 6422
GCD(338, 247) = ( 338 x 247 ) / 6422
= 338 / 247
= 338
Step2:
LCM(13, 664) = 8632
GCD(13, 664) = ( 13 x 664 ) / 8632
= 13 / 664
= 13
Step3:
LCM(1, 306) = 306
GCD(1, 306) = ( 1 x 306 ) / 306
= 1 / 306
= 1
So, Greatest Common Divisor of 338, 247, 664, 306 is 1
