Given numbers are 263,444,551,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,444,551,640 is 10294619520.
Find LCM of 263,444,551,640 with Prime Factorization
| 2 | 263, 444, 551, 640 |
| 2 | 263, 222, 551, 320 |
| 263, 111, 551, 160 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 263 x 111 x 551 x 160 = 10294619520
Therefore, the lowest common multiple of 263,444,551,640 is 10294619520.
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.
263 x 444 x 551 x 640 = 41178478080
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.
263 : 1, 263
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
551 : 1, 19, 29, 551
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,444,551,640, is 1.
Now, the common factors can be found like this.
263:263
444:2x 2x 3x 37
551:19x 29
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 41178478080/(1x4)
LCM = 41178478080/4
LCM = 10294619520
Thus, we can understand that the LCM of 263,444,551,640 is 10294619520.
