Given numbers are 455, 299, 112, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 299) = 10465
GCD(455, 299) = ( 455 x 299 ) / 10465
= 455 / 299
= 455
Step2:
LCM(13, 112) = 1456
GCD(13, 112) = ( 13 x 112 ) / 1456
= 13 / 112
= 13
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 455, 299, 112, 421 is 1
