Given numbers are 705,572,694,449,643

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

The LCM of 705,572,694,449,643 is 40399122732540.

Find LCM of 705,572,694,449,643 with Prime Factorization

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

2 x 705 x 286 x 347 x 449 x 643 = 40399122732540

Therefore, the lowest common multiple of 705,572,694,449,643 is 40399122732540.

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.

705 x 572 x 694 x 449 x 643 = 80798245465080

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

694 : 1, 2, 347, 694

449 : 1, 449

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,572,694,449,643, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

572:2x 2x 11x 13

694:2x 347

449:449

643:643

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 = 80798245465080/(1x2)

LCM = 80798245465080/2

LCM = 40399122732540

Thus, we can understand that the LCM of 705,572,694,449,643 is 40399122732540.
