Given numbers are 455,628,128,130

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

The LCM of 455,628,128,130 is 9143680.

Find LCM of 455,628,128,130 with Prime Factorization

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

2 x 2 x 5 x 13 x 7 x 157 x 32 x 1 = 9143680

Therefore, the lowest common multiple of 455,628,128,130 is 9143680.

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.

455 x 628 x 128 x 130 = 4754713600

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.

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

628 : 1, 2, 4, 157, 314, 628

128 : 1, 2, 4, 8, 16, 32, 64, 128

130 : 1, 2, 5, 10, 13, 26, 65, 130

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,628,128,130, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

628:2x 2x 157

128:2x 2x 2x 2x 2x 2x 2

130:2x 5x 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 2x 5x 13 = 520

Therefore, the value for common factors is 520.

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 = 4754713600/(1x520)

LCM = 4754713600/520

LCM = 9143680

Thus, we can understand that the LCM of 455,628,128,130 is 9143680.
