Given numbers are 953,805,441,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 953,805,441,621 is 144994185.
Find LCM of 953,805,441,621 with Prime Factorization
| 3 | 953, 805, 441, 621 |
| 3 | 953, 805, 147, 207 |
| 7 | 953, 805, 49, 69 |
| 23 | 953, 115, 7, 69 |
| 953, 5, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 23 x 953 x 5 x 7 x 3 = 144994185
Therefore, the lowest common multiple of 953,805,441,621 is 144994185.
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.
953 x 805 x 441 x 621 = 210096574065
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.
953 : 1, 953
805 : 1, 5, 7, 23, 35, 115, 161, 805
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 953,805,441,621, is 1.
Now, the common factors can be found like this.
953:953
805:5x 7x 23
441:3x 3x 7x 7
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 23 = 1449
Therefore, the value for common factors is 1449.
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 = 210096574065/(1x1449)
LCM = 210096574065/1449
LCM = 144994185
Thus, we can understand that the LCM of 953,805,441,621 is 144994185.
