Given numbers are 145,103,103,455

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

The LCM of 145,103,103,455 is 1359085.

Find LCM of 145,103,103,455 with Prime Factorization

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

5 x 103 x 29 x 1 x 1 x 91 = 1359085

Therefore, the lowest common multiple of 145,103,103,455 is 1359085.

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.

145 x 103 x 103 x 455 = 699928775

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.

145 : 1, 5, 29, 145

103 : 1, 103

103 : 1, 103

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 145,103,103,455, is 1.

Now, the common factors can be found like this.

145:5x 29

103:103

103:103

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.

5x 103 = 515

Therefore, the value for common factors is 515.

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 = 699928775/(1x515)

LCM = 699928775/515

LCM = 1359085

Thus, we can understand that the LCM of 145,103,103,455 is 1359085.
