Given numbers are 298,884,128,430,644

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

The LCM of 298,884,128,430,644 is 145899178880.

Find LCM of 298,884,128,430,644 with Prime Factorization

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

2 x 2 x 149 x 221 x 32 x 215 x 161 = 145899178880

Therefore, the lowest common multiple of 298,884,128,430,644 is 145899178880.

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.

298 x 884 x 128 x 430 x 644 = 9337547448320

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.

298 : 1, 2, 149, 298

884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,884,128,430,644, is 2.

Now, the common factors can be found like this.

298:2x 149

884:2x 2x 13x 17

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

430:2x 5x 43

644:2x 2x 7x 23

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 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 9337547448320/(2x32)

LCM = 9337547448320/64

LCM = 145899178880

Thus, we can understand that the LCM of 298,884,128,430,644 is 145899178880.
