Given numbers are 408,392,930,676,800
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,392,930,676,800 is 10473808800.
Find LCM of 408,392,930,676,800 with Prime Factorization
| 2 | 408, 392, 930, 676, 800 |
| 2 | 204, 196, 465, 338, 400 |
| 2 | 102, 98, 465, 169, 200 |
| 3 | 51, 49, 465, 169, 100 |
| 5 | 17, 49, 155, 169, 100 |
| 17, 49, 31, 169, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 49 x 31 x 169 x 20 = 10473808800
Therefore, the lowest common multiple of 408,392,930,676,800 is 10473808800.
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.
408 x 392 x 930 x 676 x 800 = 80438851584000
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,392,930,676,800, is 2.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
392:2x 2x 2x 7x 7
930:2x 3x 5x 31
676:2x 2x 13x 13
800:2x 2x 2x 2x 2x 5x 5
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 2x 2x 2x 2x 3x 5 = 3840
Therefore, the value for common factors is 3840.
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 = 80438851584000/(2x3840)
LCM = 80438851584000/7680
LCM = 10473808800
Thus, we can understand that the LCM of 408,392,930,676,800 is 10473808800.
