Given numbers are 807,254,638,470

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

The LCM of 807,254,638,470 is 15366175770.

Find LCM of 807,254,638,470 with Prime Factorization

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

2 x 807 x 127 x 319 x 235 = 15366175770

Therefore, the lowest common multiple of 807,254,638,470 is 15366175770.

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.

807 x 254 x 638 x 470 = 61464703080

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.

807 : 1, 3, 269, 807

254 : 1, 2, 127, 254

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,254,638,470, is 1.

Now, the common factors can be found like this.

807:3x 269

254:2x 127

638:2x 11x 29

470:2x 5x 47

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 61464703080/(1x4)

LCM = 61464703080/4

LCM = 15366175770

Thus, we can understand that the LCM of 807,254,638,470 is 15366175770.
