Given numbers are 702,578,143,605,728

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

The LCM of 702,578,143,605,728 is 3436753320.

Find LCM of 702,578,143,605,728 with Prime Factorization

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

2 x 11 x 13 x 27 x 289 x 1 x 55 x 28 = 3436753320

Therefore, the lowest common multiple of 702,578,143,605,728 is 3436753320.

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.

702 x 578 x 143 x 605 x 728 = 25555697687520

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

578 : 1, 2, 17, 34, 289, 578

143 : 1, 11, 13, 143

605 : 1, 5, 11, 55, 121, 605

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,578,143,605,728, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

578:2x 17x 17

143:11x 13

605:5x 11x 11

728:2x 2x 2x 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 11x 13x 13 = 7436

Therefore, the value for common factors is 7436.

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 = 25555697687520/(1x7436)

LCM = 25555697687520/7436

LCM = 3436753320

Thus, we can understand that the LCM of 702,578,143,605,728 is 3436753320.
