Given numbers are 561,160,421,726
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,160,421,726 is 415678560.
Find LCM of 561,160,421,726 with Prime Factorization
| 2 | 561, 160, 421, 726 |
| 3 | 561, 80, 421, 363 |
| 11 | 187, 80, 421, 121 |
| 17, 80, 421, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 80 x 421 x 11 = 415678560
Therefore, the lowest common multiple of 561,160,421,726 is 415678560.
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 160 x 421 x 726 = 27434784960
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
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
421 : 1, 421
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,160,421,726, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
160:2x 2x 2x 2x 2x 5
421:421
726:2x 3x 11x 11
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 = 27434784960/(1x66)
LCM = 27434784960/66
LCM = 415678560
Thus, we can understand that the LCM of 561,160,421,726 is 415678560.
