Given numbers are 545,160,696,642,840

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

The LCM of 545,160,696,642,840 is 1136442720.

Find LCM of 545,160,696,642,840 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 109 x 4 x 29 x 107 x 7 = 1136442720

Therefore, the lowest common multiple of 545,160,696,642,840 is 1136442720.

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.

545 x 160 x 696 x 642 x 840 = 32729550336000

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.

545 : 1, 5, 109, 545

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

642 : 1, 2, 3, 6, 107, 214, 321, 642

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,160,696,642,840, is 1.

Now, the common factors can be found like this.

545:5x 109

160:2x 2x 2x 2x 2x 5

696:2x 2x 2x 3x 29

642:2x 3x 107

840:2x 2x 2x 3x 5x 7

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 2x 2x 2x 2x 2x 3x 3x 5x 5 = 28800

Therefore, the value for common factors is 28800.

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 = 32729550336000/(1x28800)

LCM = 32729550336000/28800

LCM = 1136442720

Thus, we can understand that the LCM of 545,160,696,642,840 is 1136442720.
