Given numbers are 470, 181, 455, 819
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 181) = 85070
GCD(470, 181) = ( 470 x 181 ) / 85070
= 470 / 181
= 470
Step2:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
Step3:
LCM(1, 819) = 819
GCD(1, 819) = ( 1 x 819 ) / 819
= 1 / 819
= 1
So, Greatest Common Divisor of 470, 181, 455, 819 is 1
