The list of prime factors of all numbers are
Prime factors of 645 are 3 x 5 x 43
Prime factors of 955 are 5 x 191
Prime factors of 468 are 2 x 2 x 3 x 3 x 13
Prime factors of 940 are 2 x 2 x 5 x 47
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 645, 955, 468, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 955) = 123195
GCD(645, 955) = ( 645 x 955 ) / 123195
= 645 / 955
= 645
Step2:
LCM(5, 468) = 2340
GCD(5, 468) = ( 5 x 468 ) / 2340
= 5 / 468
= 5
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 645, 955, 468, 940 is 1
