Given numbers are 455,370,643,374

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

The LCM of 455,370,643,374 is 4048514470.

Find LCM of 455,370,643,374 with Prime Factorization

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

2 x 5 x 91 x 37 x 643 x 187 = 4048514470

Therefore, the lowest common multiple of 455,370,643,374 is 4048514470.

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.

455 x 370 x 643 x 374 = 40485144700

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

370 : 1, 2, 5, 10, 37, 74, 185, 370

643 : 1, 643

374 : 1, 2, 11, 17, 22, 34, 187, 374

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,370,643,374, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

370:2x 5x 37

643:643

374:2x 11x 17

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 40485144700/(1x10)

LCM = 40485144700/10

LCM = 4048514470

Thus, we can understand that the LCM of 455,370,643,374 is 4048514470.
