Given numbers are 400,756,454,923,278

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

The LCM of 400,756,454,923,278 is 2201730476400.

Find LCM of 400,756,454,923,278 with Prime Factorization

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

2 x 2 x 100 x 189 x 227 x 923 x 139 = 2201730476400

Therefore, the lowest common multiple of 400,756,454,923,278 is 2201730476400.

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.

400 x 756 x 454 x 923 x 278 = 35227687622400

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

454 : 1, 2, 227, 454

923 : 1, 13, 71, 923

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,756,454,923,278, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

756:2x 2x 3x 3x 3x 7

454:2x 227

923:13x 71

278:2x 139

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 2 = 16

Therefore, the value for common factors is 16.

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 = 35227687622400/(1x16)

LCM = 35227687622400/16

LCM = 2201730476400

Thus, we can understand that the LCM of 400,756,454,923,278 is 2201730476400.
