Given numbers are 420,523,377,523

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

The LCM of 420,523,377,523 is 82811820.

Find LCM of 420,523,377,523 with Prime Factorization

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

523 x 420 x 1 x 377 x 1 = 82811820

Therefore, the lowest common multiple of 420,523,377,523 is 82811820.

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.

420 x 523 x 377 x 523 = 43310581860

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.

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

523 : 1, 523

377 : 1, 13, 29, 377

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,523,377,523, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

523:523

377:13x 29

523:523

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

523 = 523

Therefore, the value for common factors is 523.

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 = 43310581860/(1x523)

LCM = 43310581860/523

LCM = 82811820

Thus, we can understand that the LCM of 420,523,377,523 is 82811820.
