Given numbers are 169,140,407,432

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

The LCM of 169,140,407,432 is 1039998960.

Find LCM of 169,140,407,432 with Prime Factorization

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

2 x 2 x 169 x 35 x 407 x 108 = 1039998960

Therefore, the lowest common multiple of 169,140,407,432 is 1039998960.

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.

169 x 140 x 407 x 432 = 4159995840

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.

169 : 1, 13, 169

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

407 : 1, 11, 37, 407

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,140,407,432, is 1.

Now, the common factors can be found like this.

169:13x 13

140:2x 2x 5x 7

407:11x 37

432:2x 2x 2x 2x 3x 3x 3

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4159995840/(1x4)

LCM = 4159995840/4

LCM = 1039998960

Thus, we can understand that the LCM of 169,140,407,432 is 1039998960.
