Given numbers are 715,480,918,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,480,918,423 is 493590240.
Find LCM of 715,480,918,423 with Prime Factorization
| 2 | 715, 480, 918, 423 |
| 3 | 715, 240, 459, 423 |
| 3 | 715, 80, 153, 141 |
| 5 | 715, 80, 51, 47 |
| 143, 16, 51, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 143 x 16 x 51 x 47 = 493590240
Therefore, the lowest common multiple of 715,480,918,423 is 493590240.
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.
715 x 480 x 918 x 423 = 133269364800
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,480,918,423, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
480:2x 2x 2x 2x 2x 3x 5
918:2x 3x 3x 3x 17
423:3x 3x 47
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 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 133269364800/(1x270)
LCM = 133269364800/270
LCM = 493590240
Thus, we can understand that the LCM of 715,480,918,423 is 493590240.
