Given numbers are 645,142,523,523

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

The LCM of 645,142,523,523 is 47901570.

Find LCM of 645,142,523,523 with Prime Factorization

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

523 x 645 x 142 x 1 x 1 = 47901570

Therefore, the lowest common multiple of 645,142,523,523 is 47901570.

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.

645 x 142 x 523 x 523 = 25052521110

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

142 : 1, 2, 71, 142

523 : 1, 523

523 : 1, 523

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,142,523,523, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

142:2x 71

523:523

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 = 25052521110/(1x523)

LCM = 25052521110/523

LCM = 47901570

Thus, we can understand that the LCM of 645,142,523,523 is 47901570.
