Given numbers are 403,323,785,689

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

The LCM of 403,323,785,689 is 5415681245.

Find LCM of 403,323,785,689 with Prime Factorization

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

13 x 31 x 323 x 785 x 53 = 5415681245

Therefore, the lowest common multiple of 403,323,785,689 is 5415681245.

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.

403 x 323 x 785 x 689 = 70403856185

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.

403 : 1, 13, 31, 403

323 : 1, 17, 19, 323

785 : 1, 5, 157, 785

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,323,785,689, is 1.

Now, the common factors can be found like this.

403:13x 31

323:17x 19

785:5x 157

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.

13 = 13

Therefore, the value for common factors is 13.

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 = 70403856185/(1x13)

LCM = 70403856185/13

LCM = 5415681245

Thus, we can understand that the LCM of 403,323,785,689 is 5415681245.

Here are some samples of LCM of two or more Numbers calculations.
