Given numbers are 684,598,420,935
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,598,420,935 is 1338557220.
Find LCM of 684,598,420,935 with Prime Factorization
| 2 | 684, 598, 420, 935 |
| 2 | 342, 299, 210, 935 |
| 3 | 171, 299, 105, 935 |
| 5 | 57, 299, 35, 935 |
| 57, 299, 7, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 57 x 299 x 7 x 187 = 1338557220
Therefore, the lowest common multiple of 684,598,420,935 is 1338557220.
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.
684 x 598 x 420 x 935 = 160626866400
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
598 : 1, 2, 13, 23, 26, 46, 299, 598
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,598,420,935, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
598:2x 13x 23
420:2x 2x 3x 5x 7
935:5x 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 2x 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 160626866400/(1x120)
LCM = 160626866400/120
LCM = 1338557220
Thus, we can understand that the LCM of 684,598,420,935 is 1338557220.
