The list of prime factors of all numbers are
Prime factors of 133 are 7 x 19
Prime factors of 357 are 3 x 7 x 17
Prime factors of 18 are 2 x 3 x 3
Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 133, 357, 18, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(133, 357) = 6783
GCD(133, 357) = ( 133 x 357 ) / 6783
= 133 / 357
= 133
Step2:
LCM(7, 18) = 126
GCD(7, 18) = ( 7 x 18 ) / 126
= 7 / 18
= 7
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 133, 357, 18, 648 is 1
