Prime factors of 731 are 17 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 623, 403, 495, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 403) = 251069
GCD(623, 403) = ( 623 x 403 ) / 251069
= 623 / 403
= 623
Step2:
LCM(1, 495) = 495
GCD(1, 495) = ( 1 x 495 ) / 495
= 1 / 495
= 1
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 623, 403, 495, 731 is 1
