Given numbers are 423,369,530,954,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,369,530,954,821 is 7546459590.
Find LCM of 423,369,530,954,821 with Prime Factorization
| 2 | 423, 369, 530, 954, 821 |
| 3 | 423, 369, 265, 477, 821 |
| 3 | 141, 123, 265, 159, 821 |
| 53 | 47, 41, 265, 53, 821 |
| 47, 41, 5, 1, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 53 x 47 x 41 x 5 x 1 x 821 = 7546459590
Therefore, the lowest common multiple of 423,369,530,954,821 is 7546459590.
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.
423 x 369 x 530 x 954 x 821 = 64793902039740
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.
423 : 1, 3, 9, 47, 141, 423
369 : 1, 3, 9, 41, 123, 369
530 : 1, 2, 5, 10, 53, 106, 265, 530
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,369,530,954,821, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
369:3x 3x 41
530:2x 5x 53
954:2x 3x 3x 53
821:821
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 3x 53 = 8586
Therefore, the value for common factors is 8586.
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 = 64793902039740/(1x8586)
LCM = 64793902039740/8586
LCM = 7546459590
Thus, we can understand that the LCM of 423,369,530,954,821 is 7546459590.
