Given numbers are 405, 820, 845, 372
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 820) = 66420
GCD(405, 820) = ( 405 x 820 ) / 66420
= 405 / 820
= 405
Step2:
LCM(5, 845) = 845
GCD(5, 845) = ( 5 x 845 ) / 845
= 5 / 845
= 5
Step3:
LCM(5, 372) = 1860
GCD(5, 372) = ( 5 x 372 ) / 1860
= 5 / 372
= 5
So, Greatest Common Divisor of 405, 820, 845, 372 is 1
