Given numbers are 537,718,404,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 537,718,404,420 is 2725951620.
Find LCM of 537,718,404,420 with Prime Factorization
| 2 | 537, 718, 404, 420 |
| 2 | 537, 359, 202, 210 |
| 3 | 537, 359, 101, 105 |
| 179, 359, 101, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 179 x 359 x 101 x 35 = 2725951620
Therefore, the lowest common multiple of 537,718,404,420 is 2725951620.
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.
537 x 718 x 404 x 420 = 65422838880
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.
537 : 1, 3, 179, 537
718 : 1, 2, 359, 718
404 : 1, 2, 4, 101, 202, 404
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 537,718,404,420, is 1.
Now, the common factors can be found like this.
537:3x 179
718:2x 359
404:2x 2x 101
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 3 = 24
Therefore, the value for common factors is 24.
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 = 65422838880/(1x24)
LCM = 65422838880/24
LCM = 2725951620
Thus, we can understand that the LCM of 537,718,404,420 is 2725951620.
