Given numbers are 378,530,321,169

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

The LCM of 378,530,321,169 is 1811374110.

Find LCM of 378,530,321,169 with Prime Factorization

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

2 x 3 x 63 x 265 x 107 x 169 = 1811374110

Therefore, the lowest common multiple of 378,530,321,169 is 1811374110.

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.

378 x 530 x 321 x 169 = 10868244660

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.

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

530 : 1, 2, 5, 10, 53, 106, 265, 530

321 : 1, 3, 107, 321

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,530,321,169, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

530:2x 5x 53

321:3x 107

169:13x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 10868244660/(1x6)

LCM = 10868244660/6

LCM = 1811374110

Thus, we can understand that the LCM of 378,530,321,169 is 1811374110.
