GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 571) = 318618
GCD(558, 571) = ( 558 x 571 ) / 318618
= 558 / 571
= 558
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
Step3:
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
= 1 / 930
= 1
So, Greatest Common Divisor of 558, 571, 420, 930 is 1
