Given numbers are 993,220,380,155,455

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

The LCM of 993,220,380,155,455 is 11709237540.

Find LCM of 993,220,380,155,455 with Prime Factorization

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

2 x 2 x 5 x 993 x 11 x 19 x 31 x 91 = 11709237540

Therefore, the lowest common multiple of 993,220,380,155,455 is 11709237540.

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.

993 x 220 x 380 x 155 x 455 = 5854618770000

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.

993 : 1, 3, 331, 993

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

155 : 1, 5, 31, 155

455 : 1, 5, 7, 13, 35, 65, 91, 455

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,220,380,155,455, is 1.

Now, the common factors can be found like this.

993:3x 331

220:2x 2x 5x 11

380:2x 2x 5x 19

155:5x 31

455:5x 7x 13

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 5x 5x 5 = 500

Therefore, the value for common factors is 500.

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 = 5854618770000/(1x500)

LCM = 5854618770000/500

LCM = 11709237540

Thus, we can understand that the LCM of 993,220,380,155,455 is 11709237540.
