Given numbers are 445, 220, 933, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 220) = 19580
GCD(445, 220) = ( 445 x 220 ) / 19580
= 445 / 220
= 445
Step2:
LCM(5, 933) = 4665
GCD(5, 933) = ( 5 x 933 ) / 4665
= 5 / 933
= 5
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 445, 220, 933, 665 is 1
