Calculate the LCM of 720,917,849,229

Given numbers are 720,917,849,229

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

The LCM of 720,917,849,229 is 42788173680.

Find LCM of 720,917,849,229 with Prime Factorization


3 720, 917, 849, 229
240, 917, 283, 229

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

3 x 240 x 917 x 283 x 229 = 42788173680

Therefore, the lowest common multiple of 720,917,849,229 is 42788173680.

LCM Formula to Find Lowest Common Multiple of 720,917,849,229

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 917 x 849 x 229 = 128364521040

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

917 : 1, 7, 131, 917

849 : 1, 3, 283, 849

229 : 1, 229

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,917,849,229, is 1.

Now, the common factors can be found like this.

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

917:7x 131

849:3x 283

229:229

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 128364521040/(1x3)

LCM = 128364521040/3

LCM = 42788173680

Thus, we can understand that the LCM of 720,917,849,229 is 42788173680.
