Given numbers are 168,402,491,454

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

The LCM of 168,402,491,454 is 1254559992.

Find LCM of 168,402,491,454 with Prime Factorization

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

2 x 3 x 28 x 67 x 491 x 227 = 1254559992

Therefore, the lowest common multiple of 168,402,491,454 is 1254559992.

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.

168 x 402 x 491 x 454 = 15054719904

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

402 : 1, 2, 3, 6, 67, 134, 201, 402

491 : 1, 491

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,402,491,454, is 1.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

402:2x 3x 67

491:491

454:2x 227

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 3 = 12

Therefore, the value for common factors is 12.

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 = 15054719904/(1x12)

LCM = 15054719904/12

LCM = 1254559992

Thus, we can understand that the LCM of 168,402,491,454 is 1254559992.
