Given numbers are 417, 543, 345, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 543) = 75477
GCD(417, 543) = ( 417 x 543 ) / 75477
= 417 / 543
= 417
Step2:
LCM(3, 345) = 345
GCD(3, 345) = ( 3 x 345 ) / 345
= 3 / 345
= 3
Step3:
LCM(3, 421) = 1263
GCD(3, 421) = ( 3 x 421 ) / 1263
= 3 / 421
= 3
So, Greatest Common Divisor of 417, 543, 345, 421 is 1
