Given numbers are 165, 370, 748, 666
The list of prime factors of all numbers are
Prime factors of 165 are 3 x 5 x 11
Prime factors of 370 are 2 x 5 x 37
Prime factors of 748 are 2 x 2 x 11 x 17
Prime factors of 666 are 2 x 3 x 3 x 37
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 165, 370, 748, 666
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 370) = 12210
GCD(165, 370) = ( 165 x 370 ) / 12210
= 165 / 370
= 165
Step2:
LCM(5, 748) = 3740
GCD(5, 748) = ( 5 x 748 ) / 3740
= 5 / 748
= 5
Step3:
LCM(1, 666) = 666
GCD(1, 666) = ( 1 x 666 ) / 666
= 1 / 666
= 1
So, Greatest Common Divisor of 165, 370, 748, 666 is 1
