Given numbers are 672,471,146,442

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

The LCM of 672,471,146,442 is 1702096032.

Find LCM of 672,471,146,442 with Prime Factorization

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

2 x 3 x 112 x 157 x 73 x 221 = 1702096032

Therefore, the lowest common multiple of 672,471,146,442 is 1702096032.

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.

672 x 471 x 146 x 442 = 20425152384

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

471 : 1, 3, 157, 471

146 : 1, 2, 73, 146

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,471,146,442, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

471:3x 157

146:2x 73

442:2x 13x 17

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 20425152384/(1x12)

LCM = 20425152384/12

LCM = 1702096032

Thus, we can understand that the LCM of 672,471,146,442 is 1702096032.
