Given numbers are 180, 855, 469, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 855) = 3420
GCD(180, 855) = ( 180 x 855 ) / 3420
= 180 / 855
= 180
Step2:
LCM(45, 469) = 21105
GCD(45, 469) = ( 45 x 469 ) / 21105
= 45 / 469
= 45
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 180, 855, 469, 421 is 1
