Given numbers are 751,351,442,689

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

The LCM of 751,351,442,689 is 475009002.

Find LCM of 751,351,442,689 with Prime Factorization

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

13 x 751 x 27 x 34 x 53 = 475009002

Therefore, the lowest common multiple of 751,351,442,689 is 475009002.

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.

751 x 351 x 442 x 689 = 80276521338

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.

751 : 1, 751

351 : 1, 3, 9, 13, 27, 39, 117, 351

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

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,351,442,689, is 1.

Now, the common factors can be found like this.

751:751

351:3x 3x 3x 13

442:2x 13x 17

689:13x 53

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 80276521338/(1x169)

LCM = 80276521338/169

LCM = 475009002

Thus, we can understand that the LCM of 751,351,442,689 is 475009002.
