Given numbers are 640,895,176,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,895,176,762 is 480120960.
Find LCM of 640,895,176,762 with Prime Factorization
| 2 | 640, 895, 176, 762 |
| 2 | 320, 895, 88, 381 |
| 2 | 160, 895, 44, 381 |
| 2 | 80, 895, 22, 381 |
| 5 | 40, 895, 11, 381 |
| 8, 179, 11, 381 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 8 x 179 x 11 x 381 = 480120960
Therefore, the lowest common multiple of 640,895,176,762 is 480120960.
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.
640 x 895 x 176 x 762 = 76819353600
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
895 : 1, 5, 179, 895
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,895,176,762, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
895:5x 179
176:2x 2x 2x 2x 11
762:2x 3x 127
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 76819353600/(1x160)
LCM = 76819353600/160
LCM = 480120960
Thus, we can understand that the LCM of 640,895,176,762 is 480120960.
