Given numbers are 842,789,820,776,409

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

The LCM of 842,789,820,776,409 is 21612150808680.

Find LCM of 842,789,820,776,409 with Prime Factorization

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

2 x 2 x 421 x 789 x 205 x 194 x 409 = 21612150808680

Therefore, the lowest common multiple of 842,789,820,776,409 is 21612150808680.

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.

842 x 789 x 820 x 776 x 409 = 172897206469440

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.

842 : 1, 2, 421, 842

789 : 1, 3, 263, 789

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

776 : 1, 2, 4, 8, 97, 194, 388, 776

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,789,820,776,409, is 1.

Now, the common factors can be found like this.

842:2x 421

789:3x 263

820:2x 2x 5x 41

776:2x 2x 2x 97

409:409

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 2 = 8

Therefore, the value for common factors is 8.

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 = 172897206469440/(1x8)

LCM = 172897206469440/8

LCM = 21612150808680

Thus, we can understand that the LCM of 842,789,820,776,409 is 21612150808680.
