Prime factors of 583 are 11 x 53
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 669, 720, 438, 583
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 720) = 160560
GCD(669, 720) = ( 669 x 720 ) / 160560
= 669 / 720
= 669
Step2:
LCM(3, 438) = 438
GCD(3, 438) = ( 3 x 438 ) / 438
= 3 / 438
= 3
Step3:
LCM(3, 583) = 1749
GCD(3, 583) = ( 3 x 583 ) / 1749
= 3 / 583
= 3
So, Greatest Common Divisor of 669, 720, 438, 583 is 1
