Given numbers are 815,147,625,742

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

The LCM of 815,147,625,742 is 1587416250.

Find LCM of 815,147,625,742 with Prime Factorization

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

5 x 7 x 163 x 21 x 125 x 106 = 1587416250

Therefore, the lowest common multiple of 815,147,625,742 is 1587416250.

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.

815 x 147 x 625 x 742 = 55559568750

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.

815 : 1, 5, 163, 815

147 : 1, 3, 7, 21, 49, 147

625 : 1, 5, 25, 125, 625

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,147,625,742, is 1.

Now, the common factors can be found like this.

815:5x 163

147:3x 7x 7

625:5x 5x 5x 5

742:2x 7x 53

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 55559568750/(1x35)

LCM = 55559568750/35

LCM = 1587416250

Thus, we can understand that the LCM of 815,147,625,742 is 1587416250.
