Given numbers are 620, 665, 349, 667
The list of prime factors of all numbers are
Prime factors of 620 are 2 x 2 x 5 x 31
Prime factors of 665 are 5 x 7 x 19
Prime factors of 349 are 349
Prime factors of 667 are 23 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 620, 665, 349, 667
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 665) = 82460
GCD(620, 665) = ( 620 x 665 ) / 82460
= 620 / 665
= 620
Step2:
LCM(5, 349) = 1745
GCD(5, 349) = ( 5 x 349 ) / 1745
= 5 / 349
= 5
Step3:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
So, Greatest Common Divisor of 620, 665, 349, 667 is 1
