Given numbers are 432, 648, 545, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 648) = 1296
GCD(432, 648) = ( 432 x 648 ) / 1296
= 432 / 648
= 432
Step2:
LCM(216, 545) = 117720
GCD(216, 545) = ( 216 x 545 ) / 117720
= 216 / 545
= 216
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 432, 648, 545, 809 is 1
