GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 189) = 11718
GCD(558, 189) = ( 558 x 189 ) / 11718
= 558 / 189
= 558
Step2:
LCM(9, 720) = 720
GCD(9, 720) = ( 9 x 720 ) / 720
= 9 / 720
= 9
Step3:
LCM(9, 679) = 6111
GCD(9, 679) = ( 9 x 679 ) / 6111
= 9 / 679
= 9
So, Greatest Common Divisor of 558, 189, 720, 679 is 1
