Given numbers are 928,712,820,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 928,712,820,551 is 321695840.
Find LCM of 928,712,820,551 with Prime Factorization
2 | 928, 712, 820, 551 |
2 | 464, 356, 410, 551 |
2 | 232, 178, 205, 551 |
29 | 116, 89, 205, 551 |
4, 89, 205, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 29 x 4 x 89 x 205 x 19 = 321695840
Therefore, the lowest common multiple of 928,712,820,551 is 321695840.
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.
928 x 712 x 820 x 551 = 298533739520
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
712 : 1, 2, 4, 8, 89, 178, 356, 712
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,712,820,551, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
712:2x 2x 2x 89
820:2x 2x 5x 41
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 2x 29 = 928
Therefore, the value for common factors is 928.
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 = 298533739520/(1x928)
LCM = 298533739520/928
LCM = 321695840
Thus, we can understand that the LCM of 928,712,820,551 is 321695840.
