Given numbers are 248,556,628,554,428

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

The LCM of 248,556,628,554,428 is 160409350456.

Find LCM of 248,556,628,554,428 with Prime Factorization

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

2 x 2 x 62 x 139 x 157 x 277 x 107 = 160409350456

Therefore, the lowest common multiple of 248,556,628,554,428 is 160409350456.

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.

248 x 556 x 628 x 554 x 428 = 20532396858368

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

556 : 1, 2, 4, 139, 278, 556

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

554 : 1, 2, 277, 554

428 : 1, 2, 4, 107, 214, 428

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,556,628,554,428, is 2.

Now, the common factors can be found like this.

248:2x 2x 2x 31

556:2x 2x 139

628:2x 2x 157

554:2x 277

428:2x 2x 107

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 2x 2 = 64

Therefore, the value for common factors is 64.

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 = 20532396858368/(2x64)

LCM = 20532396858368/128

LCM = 160409350456

Thus, we can understand that the LCM of 248,556,628,554,428 is 160409350456.
