Given numbers are 451,720,206,416

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

The LCM of 451,720,206,416 is 869600160.

Find LCM of 451,720,206,416 with Prime Factorization

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

2 x 2 x 2 x 2 x 451 x 45 x 103 x 26 = 869600160

Therefore, the lowest common multiple of 451,720,206,416 is 869600160.

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.

451 x 720 x 206 x 416 = 27827205120

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.

451 : 1, 11, 41, 451

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

206 : 1, 2, 103, 206

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,720,206,416, is 1.

Now, the common factors can be found like this.

451:11x 41

720:2x 2x 2x 2x 3x 3x 5

206:2x 103

416:2x 2x 2x 2x 2x 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 2x 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 27827205120/(1x32)

LCM = 27827205120/32

LCM = 869600160

Thus, we can understand that the LCM of 451,720,206,416 is 869600160.
