Given numbers are 409,154,748,775

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

The LCM of 409,154,748,775 is 1659681100.

Find LCM of 409,154,748,775 with Prime Factorization

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

2 x 11 x 409 x 7 x 34 x 775 = 1659681100

Therefore, the lowest common multiple of 409,154,748,775 is 1659681100.

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 154 x 748 x 775 = 36512984200

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

775 : 1, 5, 25, 31, 155, 775

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,154,748,775, is 1.

Now, the common factors can be found like this.

409:409

154:2x 7x 11

748:2x 2x 11x 17

775:5x 5x 31

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 36512984200/(1x22)

LCM = 36512984200/22

LCM = 1659681100

Thus, we can understand that the LCM of 409,154,748,775 is 1659681100.
