Given numbers are 397,639,403,572

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

The LCM of 397,639,403,572 is 4498306956.

Find LCM of 397,639,403,572 with Prime Factorization

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

13 x 397 x 639 x 31 x 44 = 4498306956

Therefore, the lowest common multiple of 397,639,403,572 is 4498306956.

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.

397 x 639 x 403 x 572 = 58477990428

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.

397 : 1, 397

639 : 1, 3, 9, 71, 213, 639

403 : 1, 13, 31, 403

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,639,403,572, is 1.

Now, the common factors can be found like this.

397:397

639:3x 3x 71

403:13x 31

572:2x 2x 11x 13

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 = 58477990428/(1x13)

LCM = 58477990428/13

LCM = 4498306956

Thus, we can understand that the LCM of 397,639,403,572 is 4498306956.
