Given numbers are 428,646,143,275

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

The LCM of 428,646,143,275 is 494222300.

Find LCM of 428,646,143,275 with Prime Factorization

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

2 x 11 x 214 x 323 x 13 x 25 = 494222300

Therefore, the lowest common multiple of 428,646,143,275 is 494222300.

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.

428 x 646 x 143 x 275 = 10872890600

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.

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

143 : 1, 11, 13, 143

275 : 1, 5, 11, 25, 55, 275

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,646,143,275, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

646:2x 17x 19

143:11x 13

275:5x 5x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 10872890600/(1x22)

LCM = 10872890600/22

LCM = 494222300

Thus, we can understand that the LCM of 428,646,143,275 is 494222300.
