Find LCM of 813,781,968,972,774 with Prime Factorization
| 2 | 813, 781, 968, 972, 774 |
| 2 | 813, 781, 484, 486, 387 |
| 3 | 813, 781, 242, 243, 387 |
| 3 | 271, 781, 242, 81, 129 |
| 11 | 271, 781, 242, 27, 43 |
| 271, 71, 22, 27, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 271 x 71 x 22 x 27 x 43 = 194615634312
Therefore, the lowest common multiple of 813,781,968,972,774 is 194615634312.
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.
813 x 781 x 968 x 972 x 774 = 462406747125312
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.
813 : 1, 3, 271, 813
781 : 1, 11, 71, 781
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,781,968,972,774, is 1.
Now, the common factors can be found like this.
813:3x 271
781:11x 71
968:2x 2x 2x 11x 11
972:2x 2x 3x 3x 3x 3x 3
774:2x 3x 3x 43
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 3x 3x 11 = 2376
Therefore, the value for common factors is 2376.
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 = 462406747125312/(1x2376)
LCM = 462406747125312/2376
LCM = 194615634312
Thus, we can understand that the LCM of 813,781,968,972,774 is 194615634312.
