The list of prime factors of all numbers are
Prime factors of 645 are 3 x 5 x 43
Prime factors of 235 are 5 x 47
Prime factors of 266 are 2 x 7 x 19
Prime factors of 382 are 2 x 191
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 645, 235, 266, 382
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 235) = 30315
GCD(645, 235) = ( 645 x 235 ) / 30315
= 645 / 235
= 645
Step2:
LCM(5, 266) = 1330
GCD(5, 266) = ( 5 x 266 ) / 1330
= 5 / 266
= 5
Step3:
LCM(1, 382) = 382
GCD(1, 382) = ( 1 x 382 ) / 382
= 1 / 382
= 1
So, Greatest Common Divisor of 645, 235, 266, 382 is 1
