Given numbers are 820,931,328,436,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,931,328,436,551 is 4826341240.
Find LCM of 820,931,328,436,551 with Prime Factorization
| 2 | 820, 931, 328, 436, 551 |
| 2 | 410, 931, 164, 218, 551 |
| 19 | 205, 931, 82, 109, 551 |
| 41 | 205, 49, 82, 109, 29 |
| 5, 49, 2, 109, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 41 x 5 x 49 x 2 x 109 x 29 = 4826341240
Therefore, the lowest common multiple of 820,931,328,436,551 is 4826341240.
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.
820 x 931 x 328 x 436 x 551 = 60155517215360
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
931 : 1, 7, 19, 49, 133, 931
328 : 1, 2, 4, 8, 41, 82, 164, 328
436 : 1, 2, 4, 109, 218, 436
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,931,328,436,551, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
931:7x 7x 19
328:2x 2x 2x 41
436:2x 2x 109
551:19x 29
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 19x 41 = 12464
Therefore, the value for common factors is 12464.
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 = 60155517215360/(1x12464)
LCM = 60155517215360/12464
LCM = 4826341240
Thus, we can understand that the LCM of 820,931,328,436,551 is 4826341240.
