Given numbers are 74,172,661

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 74,172,661 is 4206604.

Find LCM of 74,172,661 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 37 x 86 x 661 = 4206604

Therefore, the lowest common multiple of 74,172,661 is 4206604.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

74 x 172 x 661 = 8413208

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

74 : 1, 2, 37, 74

172 : 1, 2, 4, 43, 86, 172

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 74,172,661, is 1.

Now, the common factors can be found like this.

74:2x 37

172:2x 2x 43

661:661

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 8413208/(1x2)

LCM = 8413208/2

LCM = 4206604

Thus, we can understand that the LCM of 74,172,661 is 4206604.
