Given numbers are 715,340,820,897,455

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

The LCM of 715,340,820,897,455 is 962821860.

Find LCM of 715,340,820,897,455 with Prime Factorization

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

2 x 2 x 5 x 13 x 11 x 17 x 41 x 69 x 7 = 962821860

Therefore, the lowest common multiple of 715,340,820,897,455 is 962821860.

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.

715 x 340 x 820 x 897 x 455 = 81358447170000

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

897 : 1, 3, 13, 23, 39, 69, 299, 897

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,340,820,897,455, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

340:2x 2x 5x 17

820:2x 2x 5x 41

897:3x 13x 23

455:5x 7x 13

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 5x 5x 13x 13 = 84500

Therefore, the value for common factors is 84500.

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 = 81358447170000/(1x84500)

LCM = 81358447170000/84500

LCM = 962821860

Thus, we can understand that the LCM of 715,340,820,897,455 is 962821860.
