Find LCM of 787,684,564,996 with Prime Factorization
| 2 | 787, 684, 564, 996 |
| 2 | 787, 342, 282, 498 |
| 3 | 787, 171, 141, 249 |
| 787, 57, 47, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 787 x 57 x 47 x 83 = 2099939508
Therefore, the lowest common multiple of 787,684,564,996 is 2099939508.
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 684 x 564 x 996 = 302391289152
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
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,684,564,996, is 1.
Now, the common factors can be found like this.
787:787
684:2x 2x 3x 3x 19
564:2x 2x 3x 47
996:2x 2x 3x 83
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 302391289152/(1x144)
LCM = 302391289152/144
LCM = 2099939508
Thus, we can understand that the LCM of 787,684,564,996 is 2099939508.
