Given numbers are 55,22,22,28,806

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

The LCM of 55,22,22,28,806 is 620620.

Find LCM of 55,22,22,28,806 with Prime Factorization

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

2 x 11 x 5 x 1 x 1 x 14 x 403 = 620620

Therefore, the lowest common multiple of 55,22,22,28,806 is 620620.

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.

55 x 22 x 22 x 28 x 806 = 600760160

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.

55 : 1, 5, 11, 55

22 : 1, 2, 11, 22

22 : 1, 2, 11, 22

28 : 1, 2, 4, 7, 14, 28

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 55,22,22,28,806, is 1.

Now, the common factors can be found like this.

55:5x 11

22:2x 11

22:2x 11

28:2x 2x 7

806:2x 13x 31

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 11x 11 = 968

Therefore, the value for common factors is 968.

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 = 600760160/(1x968)

LCM = 600760160/968

LCM = 620620

Thus, we can understand that the LCM of 55,22,22,28,806 is 620620.
