Given numbers are 450,158,991,560

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

The LCM of 450,158,991,560 is 1972882800.

Find LCM of 450,158,991,560 with Prime Factorization

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

2 x 5 x 45 x 79 x 991 x 56 = 1972882800

Therefore, the lowest common multiple of 450,158,991,560 is 1972882800.

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 158 x 991 x 560 = 39457656000

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

158 : 1, 2, 79, 158

991 : 1, 991

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,158,991,560, is 1.

Now, the common factors can be found like this.

450:2x 3x 3x 5x 5

158:2x 79

991:991

560:2x 2x 2x 2x 5x 7

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 5 = 20

Therefore, the value for common factors is 20.

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 = 39457656000/(1x20)

LCM = 39457656000/20

LCM = 1972882800

Thus, we can understand that the LCM of 450,158,991,560 is 1972882800.
