Given numbers are 405, 153, 417, 308
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 153) = 6885
GCD(405, 153) = ( 405 x 153 ) / 6885
= 405 / 153
= 405
Step2:
LCM(9, 417) = 1251
GCD(9, 417) = ( 9 x 417 ) / 1251
= 9 / 417
= 9
Step3:
LCM(3, 308) = 924
GCD(3, 308) = ( 3 x 308 ) / 924
= 3 / 308
= 3
So, Greatest Common Divisor of 405, 153, 417, 308 is 1
