Given numbers are 787,584,401,490,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,584,401,490,828 is 9346916907720.
Find LCM of 787,584,401,490,828 with Prime Factorization
| 2 | 787, 584, 401, 490, 828 |
| 2 | 787, 292, 401, 245, 414 |
| 787, 146, 401, 245, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 787 x 146 x 401 x 245 x 207 = 9346916907720
Therefore, the lowest common multiple of 787,584,401,490,828 is 9346916907720.
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.
787 x 584 x 401 x 490 x 828 = 74775335261760
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.
787 : 1, 787
584 : 1, 2, 4, 8, 73, 146, 292, 584
401 : 1, 401
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,584,401,490,828, is 1.
Now, the common factors can be found like this.
787:787
584:2x 2x 2x 73
401:401
490:2x 5x 7x 7
828:2x 2x 3x 3x 23
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 2 = 8
Therefore, the value for common factors is 8.
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 = 74775335261760/(1x8)
LCM = 74775335261760/8
LCM = 9346916907720
Thus, we can understand that the LCM of 787,584,401,490,828 is 9346916907720.
