Given numbers are 470,473,402,985,638

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

The LCM of 470,473,402,985,638 is 255281463030.

Find LCM of 470,473,402,985,638 with Prime Factorization

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

2 x 5 x 11 x 47 x 43 x 201 x 197 x 29 = 255281463030

Therefore, the lowest common multiple of 470,473,402,985,638 is 255281463030.

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.

470 x 473 x 402 x 985 x 638 = 56161921866600

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.

470 : 1, 2, 5, 10, 47, 94, 235, 470

473 : 1, 11, 43, 473

402 : 1, 2, 3, 6, 67, 134, 201, 402

985 : 1, 5, 197, 985

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,473,402,985,638, is 1.

Now, the common factors can be found like this.

470:2x 5x 47

473:11x 43

402:2x 3x 67

985:5x 197

638:2x 11x 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 2x 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 56161921866600/(1x220)

LCM = 56161921866600/220

LCM = 255281463030

Thus, we can understand that the LCM of 470,473,402,985,638 is 255281463030.
