Four factors in common.
210 is the number whose prime factors are the first four primes unrepeated.
6.To find the least common multiple, factor each number to its prime factors and then multiply all the factors from the first number with any factors in the second number that are not repeated from the first number. The prime factors of 6 are 3 and 2. 18 factored to its primes is 2 x 3 x 3. So multiply 3 and 2 from the first number (6) and ignore the factors of 18 since they repeat the factors of 6. Take the product 6, as the LCM.
12 can be factored 22 x3.So the first factor is 1, then 2,3,4,and 6. Those are the first 5 factors.
1, 2, 3, 5, 6, 10, 15, 30 - they are the only factors
1, 2, 3 and 6
They are: 1 2 3 6
1, 2, 3, 6. Four factors.
No, there are four.
The common factors are: 1, 2, 3, 4, 6, 9, 12, 18, 36.
6, 8 and 10 are some numbers with four factors.
Four factors in common.
6 is.

21 has four factors: 1, 3, 7 and 21.
