Find LCM of 143,552,465,463,640 with Prime Factorization
| 2 | 143, 552, 465, 463, 640 |
| 2 | 143, 276, 465, 463, 320 |
| 2 | 143, 138, 465, 463, 160 |
| 3 | 143, 69, 465, 463, 80 |
| 5 | 143, 23, 155, 463, 80 |
| 143, 23, 31, 463, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 143 x 23 x 31 x 463 x 16 = 90637472640
Therefore, the lowest common multiple of 143,552,465,463,640 is 90637472640.
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.
143 x 552 x 465 x 463 x 640 = 10876496716800
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.
143 : 1, 11, 13, 143
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
465 : 1, 3, 5, 15, 31, 93, 155, 465
463 : 1, 463
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 143,552,465,463,640, is 1.
Now, the common factors can be found like this.
143:11x 13
552:2x 2x 2x 3x 23
465:3x 5x 31
463:463
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 2x 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 10876496716800/(1x120)
LCM = 10876496716800/120
LCM = 90637472640
Thus, we can understand that the LCM of 143,552,465,463,640 is 90637472640.
