Given numbers are 453,91,642,810

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

The LCM of 453,91,642,810 is 1190932470.

Find LCM of 453,91,642,810 with Prime Factorization

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

2 x 3 x 151 x 91 x 107 x 135 = 1190932470

Therefore, the lowest common multiple of 453,91,642,810 is 1190932470.

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.

453 x 91 x 642 x 810 = 21436784460

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.

453 : 1, 3, 151, 453

91 : 1, 7, 13, 91

642 : 1, 2, 3, 6, 107, 214, 321, 642

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,91,642,810, is 1.

Now, the common factors can be found like this.

453:3x 151

91:7x 13

642:2x 3x 107

810:2x 3x 3x 3x 3x 5

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 21436784460/(1x18)

LCM = 21436784460/18

LCM = 1190932470

Thus, we can understand that the LCM of 453,91,642,810 is 1190932470.
