Given numbers are 720,176,442,203

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

The LCM of 720,176,442,203 is 355314960.

Find LCM of 720,176,442,203 with Prime Factorization

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

2 x 2 x 2 x 2 x 45 x 11 x 221 x 203 = 355314960

Therefore, the lowest common multiple of 720,176,442,203 is 355314960.

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.

720 x 176 x 442 x 203 = 11370078720

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.

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

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

442 : 1, 2, 13, 17, 26, 34, 221, 442

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,176,442,203, is 1.

Now, the common factors can be found like this.

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

176:2x 2x 2x 2x 11

442:2x 13x 17

203:7x 29

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 = 11370078720/(1x32)

LCM = 11370078720/32

LCM = 355314960

Thus, we can understand that the LCM of 720,176,442,203 is 355314960.
