GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(505, 430) = 43430
GCD(505, 430) = ( 505 x 430 ) / 43430
= 505 / 430
= 505
Step2:
LCM(5, 745) = 745
GCD(5, 745) = ( 5 x 745 ) / 745
= 5 / 745
= 5
Step3:
LCM(5, 405) = 405
GCD(5, 405) = ( 5 x 405 ) / 405
= 5 / 405
= 5
So, Greatest Common Divisor of 505, 430, 745, 405 is 5
