Given numbers are 596,686,648,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 596,686,648,420 is 165586680.
Find LCM of 596,686,648,420 with Prime Factorization
| 2 | 596, 686, 648, 420 |
| 2 | 298, 343, 324, 210 |
| 3 | 149, 343, 162, 105 |
| 7 | 149, 343, 54, 35 |
| 149, 49, 54, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 149 x 49 x 54 x 5 = 165586680
Therefore, the lowest common multiple of 596,686,648,420 is 165586680.
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.
596 x 686 x 648 x 420 = 111274248960
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.
596 : 1, 2, 4, 149, 298, 596
686 : 1, 2, 7, 14, 49, 98, 343, 686
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 596,686,648,420, is 2.
Now, the common factors can be found like this.
596:2x 2x 149
686:2x 7x 7x 7
648:2x 2x 2x 3x 3x 3x 3
420:2x 2x 3x 5x 7
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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 111274248960/(2x336)
LCM = 111274248960/672
LCM = 165586680
Thus, we can understand that the LCM of 596,686,648,420 is 165586680.
