Given numbers are 473,721,436,721

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

The LCM of 473,721,436,721 is 148690388.

Find LCM of 473,721,436,721 with Prime Factorization

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

7 x 103 x 473 x 1 x 436 x 1 = 148690388

Therefore, the lowest common multiple of 473,721,436,721 is 148690388.

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.

473 x 721 x 436 x 721 = 107205769748

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.

473 : 1, 11, 43, 473

721 : 1, 7, 103, 721

436 : 1, 2, 4, 109, 218, 436

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,721,436,721, is 1.

Now, the common factors can be found like this.

473:11x 43

721:7x 103

436:2x 2x 109

721:7x 103

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 107205769748/(1x721)

LCM = 107205769748/721

LCM = 148690388

Thus, we can understand that the LCM of 473,721,436,721 is 148690388.
