Given numbers are 450,985,786,440,690

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

The LCM of 450,985,786,440,690 is 11752507800.

Find LCM of 450,985,786,440,690 with Prime Factorization

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

2 x 3 x 5 x 15 x 197 x 131 x 44 x 23 = 11752507800

Therefore, the lowest common multiple of 450,985,786,440,690 is 11752507800.

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.

450 x 985 x 786 x 440 x 690 = 105772570200000

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.

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

985 : 1, 5, 197, 985

786 : 1, 2, 3, 6, 131, 262, 393, 786

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,985,786,440,690, is 1.

Now, the common factors can be found like this.

450:2x 3x 3x 5x 5

985:5x 197

786:2x 3x 131

440:2x 2x 2x 5x 11

690:2x 3x 5x 23

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 2x 3x 3x 5x 5x 5 = 9000

Therefore, the value for common factors is 9000.

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 = 105772570200000/(1x9000)

LCM = 105772570200000/9000

LCM = 11752507800

Thus, we can understand that the LCM of 450,985,786,440,690 is 11752507800.
