Given numbers are 523,520,722,841,420

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

The LCM of 523,520,722,841,420 is 1733913887160.

Find LCM of 523,520,722,841,420 with Prime Factorization

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

2 x 2 x 5 x 523 x 26 x 361 x 841 x 21 = 1733913887160

Therefore, the lowest common multiple of 523,520,722,841,420 is 1733913887160.

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.

523 x 520 x 722 x 841 x 420 = 69356555486400

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.

523 : 1, 523

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

722 : 1, 2, 19, 38, 361, 722

841 : 1, 29, 841

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,520,722,841,420, is 1.

Now, the common factors can be found like this.

523:523

520:2x 2x 2x 5x 13

722:2x 19x 19

841:29x 29

420:2x 2x 3x 5x 7

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 5 = 40

Therefore, the value for common factors is 40.

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 = 69356555486400/(1x40)

LCM = 69356555486400/40

LCM = 1733913887160

Thus, we can understand that the LCM of 523,520,722,841,420 is 1733913887160.
