Given numbers are 303, 305, 644, 394
The list of prime factors of all numbers are
Prime factors of 303 are 3 x 101
Prime factors of 305 are 5 x 61
Prime factors of 644 are 2 x 2 x 7 x 23
Prime factors of 394 are 2 x 197
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 303, 305, 644, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(303, 305) = 92415
GCD(303, 305) = ( 303 x 305 ) / 92415
= 303 / 305
= 303
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 303, 305, 644, 394 is 1
