Given numbers are 917,701,784,411,513
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,701,784,411,513 is 5059916016624.
Find LCM of 917,701,784,411,513 with Prime Factorization
| 3 | 917, 701, 784, 411, 513 |
| 7 | 917, 701, 784, 137, 171 |
| 131, 701, 112, 137, 171 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 131 x 701 x 112 x 137 x 171 = 5059916016624
Therefore, the lowest common multiple of 917,701,784,411,513 is 5059916016624.
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.
917 x 701 x 784 x 411 x 513 = 106258236349104
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.
917 : 1, 7, 131, 917
701 : 1, 701
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
411 : 1, 3, 137, 411
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,701,784,411,513, is 1.
Now, the common factors can be found like this.
917:7x 131
701:701
784:2x 2x 2x 2x 7x 7
411:3x 137
513:3x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 106258236349104/(1x21)
LCM = 106258236349104/21
LCM = 5059916016624
Thus, we can understand that the LCM of 917,701,784,411,513 is 5059916016624.
