Given numbers are 409,838,578,757

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

The LCM of 409,838,578,757 is 74982695566.

Find LCM of 409,838,578,757 with Prime Factorization

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

2 x 409 x 419 x 289 x 757 = 74982695566

Therefore, the lowest common multiple of 409,838,578,757 is 74982695566.

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.

409 x 838 x 578 x 757 = 149965391132

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.

409 : 1, 409

838 : 1, 2, 419, 838

578 : 1, 2, 17, 34, 289, 578

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,838,578,757, is 1.

Now, the common factors can be found like this.

409:409

838:2x 419

578:2x 17x 17

757:757

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

2 = 2

Therefore, the value for common factors is 2.

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 = 149965391132/(1x2)

LCM = 149965391132/2

LCM = 74982695566

Thus, we can understand that the LCM of 409,838,578,757 is 74982695566.
