Given numbers are 746,514,478,221

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

The LCM of 746,514,478,221 is 10126564318.

Find LCM of 746,514,478,221 with Prime Factorization

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

2 x 373 x 257 x 239 x 221 = 10126564318

Therefore, the lowest common multiple of 746,514,478,221 is 10126564318.

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.

746 x 514 x 478 x 221 = 40506257272

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.

746 : 1, 2, 373, 746

514 : 1, 2, 257, 514

478 : 1, 2, 239, 478

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 746,514,478,221, is 1.

Now, the common factors can be found like this.

746:2x 373

514:2x 257

478:2x 239

221:13x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 40506257272/(1x4)

LCM = 40506257272/4

LCM = 10126564318

Thus, we can understand that the LCM of 746,514,478,221 is 10126564318.
