There are an infinite number of integers with "only 7 factors". Any number which is the product of exactly 7 prime numbers.

The least common multiple is the least factor that can be common in every number. In algebra , L.C.M of 19, 7 and 4 is 19 *7* 4 =532. 532 is the least common multiple of 19 7 and 4.
You multiply the factors together. if the factors are 6 and 7 or 2,3 and 7, then the number is 6x7=2x3x7=42
119 is a composite number; it has factors other than 1 and itself.The four factors of 119 are 1, 7, 17, and 119.The factor pairs of 119 are 1 x 119 and 7 x 17.The proper factors of 119 are 1, 7, and 17 or,if the definition you are using excludes 1, they are 7 and 17.The prime factors of 119 are 7 and 17.The 2 distinct prime factors (listing each prime factor only once) of 119 are 7 and 17.The prime factorization of 119 is 7 x 17.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple of a single number because "common" refers to factors or multiples that two or more numbers have in common.

3*5*7*9 = 945 ...check if any number less than that has exactly four distinct factors.
A number that has exactly two (positive) factors is called a prime number. For instance, the only factors of 7 are 1 and 7.
729 is the second number with exactly 7.
There are an infinite number of integers with "only 7 factors". Any number which is the product of exactly 7 prime numbers.

The expression 2x3x4x5 can be simplified to 120. The number 120 has the least number of factors because it is a product of consecutive prime numbers (2, 3, and 5). When a number is a product of distinct prime numbers, it will have fewer factors compared to numbers with repeated prime factors. In this case, 120 only has 16 factors, making it the least among numbers with the same number of prime factors.
All prime squares have exactly three factors.49 has exactly three factors: 1, 7, and 49.

Any number that is the 6th power of a prime integer.
Their common factors are 1 and 7 .
