Given numbers are 645,202,497,724

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

The LCM of 645,202,497,724 is 23440995060.

Find LCM of 645,202,497,724 with Prime Factorization

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

2 x 645 x 101 x 497 x 362 = 23440995060

Therefore, the lowest common multiple of 645,202,497,724 is 23440995060.

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 202 x 497 x 724 = 46881990120

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

202 : 1, 2, 101, 202

497 : 1, 7, 71, 497

724 : 1, 2, 4, 181, 362, 724

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,202,497,724, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

202:2x 101

497:7x 71

724:2x 2x 181

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

2 = 2

Therefore, the value for common factors is 2.

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 = 46881990120/(1x2)

LCM = 46881990120/2

LCM = 23440995060

Thus, we can understand that the LCM of 645,202,497,724 is 23440995060.
