Given numbers are 330, 251, 761, 645
The list of prime factors of all numbers are
Prime factors of 330 are 2 x 3 x 5 x 11
Prime factors of 251 are 251
Prime factors of 761 are 761
Prime factors of 645 are 3 x 5 x 43
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 330, 251, 761, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(330, 251) = 82830
GCD(330, 251) = ( 330 x 251 ) / 82830
= 330 / 251
= 330
Step2:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 330, 251, 761, 645 is 1
