Given numbers are 445, 154, 647, 344
The list of prime factors of all numbers are
Prime factors of 445 are 5 x 89
Prime factors of 154 are 2 x 7 x 11
Prime factors of 647 are 647
Prime factors of 344 are 2 x 2 x 2 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 445, 154, 647, 344
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 154) = 68530
GCD(445, 154) = ( 445 x 154 ) / 68530
= 445 / 154
= 445
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 344) = 344
GCD(1, 344) = ( 1 x 344 ) / 344
= 1 / 344
= 1
So, Greatest Common Divisor of 445, 154, 647, 344 is 1
