Given numbers are 630,257,307,557,406

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

The LCM of 630,257,307,557,406 is 802906994610.

Find LCM of 630,257,307,557,406 with Prime Factorization

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

2 x 7 x 45 x 257 x 307 x 557 x 29 = 802906994610

Therefore, the lowest common multiple of 630,257,307,557,406 is 802906994610.

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.

630 x 257 x 307 x 557 x 406 = 11240697924540

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

257 : 1, 257

307 : 1, 307

557 : 1, 557

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,257,307,557,406, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

257:257

307:307

557:557

406:2x 7x 29

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 11240697924540/(1x14)

LCM = 11240697924540/14

LCM = 802906994610

Thus, we can understand that the LCM of 630,257,307,557,406 is 802906994610.
