Given numbers are 420,604,569,834,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,604,569,834,431 is 2161874975820.
Find LCM of 420,604,569,834,431 with Prime Factorization
| 2 | 420, 604, 569, 834, 431 |
| 2 | 210, 302, 569, 417, 431 |
| 3 | 105, 151, 569, 417, 431 |
| 35, 151, 569, 139, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 35 x 151 x 569 x 139 x 431 = 2161874975820
Therefore, the lowest common multiple of 420,604,569,834,431 is 2161874975820.
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.
420 x 604 x 569 x 834 x 431 = 51884999419680
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.
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
604 : 1, 2, 4, 151, 302, 604
569 : 1, 569
834 : 1, 2, 3, 6, 139, 278, 417, 834
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,604,569,834,431, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
604:2x 2x 151
569:569
834:2x 3x 139
431:431
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 = 51884999419680/(1x24)
LCM = 51884999419680/24
LCM = 2161874975820
Thus, we can understand that the LCM of 420,604,569,834,431 is 2161874975820.
