Given numbers are 989,638,232,545

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

The LCM of 989,638,232,545 is 1375540760.

Find LCM of 989,638,232,545 with Prime Factorization

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

2 x 29 x 989 x 11 x 4 x 545 = 1375540760

Therefore, the lowest common multiple of 989,638,232,545 is 1375540760.

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 638 x 232 x 545 = 79781364080

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

232 : 1, 2, 4, 8, 29, 58, 116, 232

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,638,232,545, is 1.

Now, the common factors can be found like this.

989:23x 43

638:2x 11x 29

232:2x 2x 2x 29

545:5x 109

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

2x 29 = 58

Therefore, the value for common factors is 58.

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 = 79781364080/(1x58)

LCM = 79781364080/58

LCM = 1375540760

Thus, we can understand that the LCM of 989,638,232,545 is 1375540760.
