GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 129) = 23994
GCD(558, 129) = ( 558 x 129 ) / 23994
= 558 / 129
= 558
Step2:
LCM(3, 405) = 405
GCD(3, 405) = ( 3 x 405 ) / 405
= 3 / 405
= 3
Step3:
LCM(3, 319) = 957
GCD(3, 319) = ( 3 x 319 ) / 957
= 3 / 319
= 3
So, Greatest Common Divisor of 558, 129, 405, 319 is 1
