Given numbers are 645,982,602,758

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

The LCM of 645,982,602,758 is 1680383670.

Find LCM of 645,982,602,758 with Prime Factorization

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

2 x 43 x 15 x 491 x 7 x 379 = 1680383670

Therefore, the lowest common multiple of 645,982,602,758 is 1680383670.

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 982 x 602 x 758 = 289025991240

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

982 : 1, 2, 491, 982

602 : 1, 2, 7, 14, 43, 86, 301, 602

758 : 1, 2, 379, 758

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,982,602,758, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

982:2x 491

602:2x 7x 43

758:2x 379

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 43 = 172

Therefore, the value for common factors is 172.

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 = 289025991240/(1x172)

LCM = 289025991240/172

LCM = 1680383670

Thus, we can understand that the LCM of 645,982,602,758 is 1680383670.
