Given numbers are 287,613,581,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,613,581,251 is 3665170523.
Find LCM of 287,613,581,251 with Prime Factorization
| 7 | 287, 613, 581, 251 |
| 41, 613, 83, 251 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 613 x 83 x 251 = 3665170523
Therefore, the lowest common multiple of 287,613,581,251 is 3665170523.
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.
287 x 613 x 581 x 251 = 25656193661
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.
287 : 1, 7, 41, 287
613 : 1, 613
581 : 1, 7, 83, 581
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,613,581,251, is 1.
Now, the common factors can be found like this.
287:7x 41
613:613
581:7x 83
251:251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 25656193661/(1x7)
LCM = 25656193661/7
LCM = 3665170523
Thus, we can understand that the LCM of 287,613,581,251 is 3665170523.
