Given numbers are 598,923,810,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 598,923,810,781 is 189150390.
Find LCM of 598,923,810,781 with Prime Factorization
| 2 | 598, 923, 810, 781 |
| 13 | 299, 923, 405, 781 |
| 71 | 23, 71, 405, 781 |
| 23, 1, 405, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 71 x 23 x 1 x 405 x 11 = 189150390
Therefore, the lowest common multiple of 598,923,810,781 is 189150390.
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 923 x 810 x 781 = 349171619940
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
923 : 1, 13, 71, 923
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,923,810,781, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
923:13x 71
810:2x 3x 3x 3x 3x 5
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 71 = 1846
Therefore, the value for common factors is 1846.
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 = 349171619940/(1x1846)
LCM = 349171619940/1846
LCM = 189150390
Thus, we can understand that the LCM of 598,923,810,781 is 189150390.
