Find LCM of 640,716,848,215,188 with Prime Factorization
| 2 | 640, 716, 848, 215, 188 |
| 2 | 320, 358, 424, 215, 94 |
| 2 | 160, 179, 212, 215, 47 |
| 2 | 80, 179, 106, 215, 47 |
| 5 | 40, 179, 53, 215, 47 |
| 8, 179, 53, 43, 47 |
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 53 x 43 x 47 = 12270865280
Therefore, the lowest common multiple of 640,716,848,215,188 is 12270865280.
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 716 x 848 x 215 x 188 = 15706707558400
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
716 : 1, 2, 4, 179, 358, 716
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
215 : 1, 5, 43, 215
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,716,848,215,188, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
716:2x 2x 179
848:2x 2x 2x 2x 53
215:5x 43
188:2x 2x 47
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 2x 2x 2x 5 = 1280
Therefore, the value for common factors is 1280.
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 = 15706707558400/(1x1280)
LCM = 15706707558400/1280
LCM = 12270865280
Thus, we can understand that the LCM of 640,716,848,215,188 is 12270865280.
