Given numbers are 989,415,636,645,702

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

The LCM of 989,415,636,645,702 is 30541289220.

Find LCM of 989,415,636,645,702 with Prime Factorization

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

2 x 3 x 5 x 43 x 23 x 83 x 106 x 1 x 117 = 30541289220

Therefore, the lowest common multiple of 989,415,636,645,702 is 30541289220.

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.

989 x 415 x 636 x 645 x 702 = 118194789281400

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.

989 : 1, 23, 43, 989

415 : 1, 5, 83, 415

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,415,636,645,702, is 1.

Now, the common factors can be found like this.

989:23x 43

415:5x 83

636:2x 2x 3x 53

645:3x 5x 43

702:2x 3x 3x 3x 13

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

2x 3x 3x 5x 43 = 3870

Therefore, the value for common factors is 3870.

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 = 118194789281400/(1x3870)

LCM = 118194789281400/3870

LCM = 30541289220

Thus, we can understand that the LCM of 989,415,636,645,702 is 30541289220.
