Given numbers are 598,938,642,670,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 598,938,642,670,989 is 19356084930.
Find LCM of 598,938,642,670,989 with Prime Factorization
| 2 | 598, 938, 642, 670, 989 |
| 23 | 299, 469, 321, 335, 989 |
| 67 | 13, 469, 321, 335, 43 |
| 13, 7, 321, 5, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 67 x 13 x 7 x 321 x 5 x 43 = 19356084930
Therefore, the lowest common multiple of 598,938,642,670,989 is 19356084930.
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.
598 x 938 x 642 x 670 x 989 = 238621815017040
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
938 : 1, 2, 7, 14, 67, 134, 469, 938
642 : 1, 2, 3, 6, 107, 214, 321, 642
670 : 1, 2, 5, 10, 67, 134, 335, 670
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,938,642,670,989, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
938:2x 7x 67
642:2x 3x 107
670:2x 5x 67
989:23x 43
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 2x 23x 67 = 12328
Therefore, the value for common factors is 12328.
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 = 238621815017040/(1x12328)
LCM = 238621815017040/12328
LCM = 19356084930
Thus, we can understand that the LCM of 598,938,642,670,989 is 19356084930.
