Given numbers are 513,391,688,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,391,688,374 is 1518012144.
Find LCM of 513,391,688,374 with Prime Factorization
| 2 | 513, 391, 688, 374 |
| 17 | 513, 391, 344, 187 |
| 513, 23, 344, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 513 x 23 x 344 x 11 = 1518012144
Therefore, the lowest common multiple of 513,391,688,374 is 1518012144.
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.
513 x 391 x 688 x 374 = 51612412896
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
391 : 1, 17, 23, 391
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,391,688,374, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
391:17x 23
688:2x 2x 2x 2x 43
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 51612412896/(1x34)
LCM = 51612412896/34
LCM = 1518012144
Thus, we can understand that the LCM of 513,391,688,374 is 1518012144.
