Given numbers are 661,543,290,376
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,543,290,376 is 19568481960.
Find LCM of 661,543,290,376 with Prime Factorization
| 2 | 661, 543, 290, 376 |
| 661, 543, 145, 188 |
Multiply the prime numbers at the bottom and the left side.
2 x 661 x 543 x 145 x 188 = 19568481960
Therefore, the lowest common multiple of 661,543,290,376 is 19568481960.
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.
661 x 543 x 290 x 376 = 39136963920
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.
661 : 1, 661
543 : 1, 3, 181, 543
290 : 1, 2, 5, 10, 29, 58, 145, 290
376 : 1, 2, 4, 8, 47, 94, 188, 376
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,543,290,376, is 1.
Now, the common factors can be found like this.
661:661
543:3x 181
290:2x 5x 29
376:2x 2x 2x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 39136963920/(1x2)
LCM = 39136963920/2
LCM = 19568481960
Thus, we can understand that the LCM of 661,543,290,376 is 19568481960.
