Given numbers are 180, 638, 443, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 638) = 57420
GCD(180, 638) = ( 180 x 638 ) / 57420
= 180 / 638
= 180
Step2:
LCM(2, 443) = 886
GCD(2, 443) = ( 2 x 443 ) / 886
= 2 / 443
= 2
Step3:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
So, Greatest Common Divisor of 180, 638, 443, 909 is 1
