Given numbers are 84,91,14,53,406

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

The LCM of 84,91,14,53,406 is 1678404.

Find LCM of 84,91,14,53,406 with Prime Factorization

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

2 x 7 x 6 x 13 x 1 x 53 x 29 = 1678404

Therefore, the lowest common multiple of 84,91,14,53,406 is 1678404.

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.

84 x 91 x 14 x 53 x 406 = 2302770288

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.

84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

91 : 1, 7, 13, 91

14 : 1, 2, 7, 14

53 : 1, 53

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 84,91,14,53,406, is 1.

Now, the common factors can be found like this.

84:2x 2x 3x 7

91:7x 13

14:2x 7

53:53

406:2x 7x 29

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 7x 7x 7 = 1372

Therefore, the value for common factors is 1372.

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 = 2302770288/(1x1372)

LCM = 2302770288/1372

LCM = 1678404

Thus, we can understand that the LCM of 84,91,14,53,406 is 1678404.
