Given numbers are 826,311,128,722,780

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

The LCM of 826,311,128,722,780 is 1157343358080.

Find LCM of 826,311,128,722,780 with Prime Factorization

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

2 x 2 x 413 x 311 x 32 x 361 x 195 = 1157343358080

Therefore, the lowest common multiple of 826,311,128,722,780 is 1157343358080.

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.

826 x 311 x 128 x 722 x 780 = 18517493729280

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.

826 : 1, 2, 7, 14, 59, 118, 413, 826

311 : 1, 311

128 : 1, 2, 4, 8, 16, 32, 64, 128

722 : 1, 2, 19, 38, 361, 722

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,311,128,722,780, is 1.

Now, the common factors can be found like this.

826:2x 7x 59

311:311

128:2x 2x 2x 2x 2x 2x 2

722:2x 19x 19

780:2x 2x 3x 5x 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 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 = 18517493729280/(1x16)

LCM = 18517493729280/16

LCM = 1157343358080

Thus, we can understand that the LCM of 826,311,128,722,780 is 1157343358080.
