Given numbers are 561,294,851,664,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,294,851,664,517 is 730053081912.
Find LCM of 561,294,851,664,517 with Prime Factorization
| 2 | 561, 294, 851, 664, 517 |
| 3 | 561, 147, 851, 332, 517 |
| 11 | 187, 49, 851, 332, 517 |
| 17, 49, 851, 332, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 49 x 851 x 332 x 47 = 730053081912
Therefore, the lowest common multiple of 561,294,851,664,517 is 730053081912.
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.
561 x 294 x 851 x 664 x 517 = 48183503406192
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
851 : 1, 23, 37, 851
664 : 1, 2, 4, 8, 83, 166, 332, 664
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,294,851,664,517, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
294:2x 3x 7x 7
851:23x 37
664:2x 2x 2x 83
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 48183503406192/(1x66)
LCM = 48183503406192/66
LCM = 730053081912
Thus, we can understand that the LCM of 561,294,851,664,517 is 730053081912.
