Find LCM of 787,715,663,480,956 with Prime Factorization
| 2 | 787, 715, 663, 480, 956 |
| 2 | 787, 715, 663, 240, 478 |
| 3 | 787, 715, 663, 120, 239 |
| 5 | 787, 715, 221, 40, 239 |
| 13 | 787, 143, 221, 8, 239 |
| 787, 11, 17, 8, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 787 x 11 x 17 x 8 x 239 = 219481959840
Therefore, the lowest common multiple of 787,715,663,480,956 is 219481959840.
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.
787 x 715 x 663 x 480 x 956 = 171195928675200
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.
787 : 1, 787
715 : 1, 5, 11, 13, 55, 65, 143, 715
663 : 1, 3, 13, 17, 39, 51, 221, 663
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,715,663,480,956, is 1.
Now, the common factors can be found like this.
787:787
715:5x 11x 13
663:3x 13x 17
480:2x 2x 2x 2x 2x 3x 5
956:2x 2x 239
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 171195928675200/(1x780)
LCM = 171195928675200/780
LCM = 219481959840
Thus, we can understand that the LCM of 787,715,663,480,956 is 219481959840.
