Answer: the common factor is 6
Explanation:
the factor of 30=1x2x3x5
the factor of 18=1x2x3x3
the numbers that are common for both numbers are1, 2 and 3
Answer:
6
Use prime factorization;
30 = 2 * 3* 5
18 = 2 * 3 * 3
Both of these numbers have ( 2 * 3 ) in common, ( 2 * 3 = 6 ), hence their highest common factor (greatest common factor) is 6.
