GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 225) = 22725
GCD(909, 225) = ( 909 x 225 ) / 22725
= 909 / 225
= 909
Step2:
LCM(9, 575) = 5175
GCD(9, 575) = ( 9 x 575 ) / 5175
= 9 / 575
= 9
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 909, 225, 575, 620 is 1
