Given numbers are 211,780,720,291

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

The LCM of 211,780,720,291 is 191571120.

Find LCM of 211,780,720,291 with Prime Factorization

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

2 x 2 x 3 x 5 x 211 x 13 x 12 x 97 = 191571120

Therefore, the lowest common multiple of 211,780,720,291 is 191571120.

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.

211 x 780 x 720 x 291 = 34482801600

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.

211 : 1, 211

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

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

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,780,720,291, is 1.

Now, the common factors can be found like this.

211:211

780:2x 2x 3x 5x 13

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

291:3x 97

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 34482801600/(1x180)

LCM = 34482801600/180

LCM = 191571120

Thus, we can understand that the LCM of 211,780,720,291 is 191571120.
