Find LCM of 660,764,946,752,387 with Prime Factorization
| 2 | 660, 764, 946, 752, 387 |
| 2 | 330, 382, 473, 376, 387 |
| 3 | 165, 191, 473, 188, 387 |
| 11 | 55, 191, 473, 188, 129 |
| 43 | 5, 191, 43, 188, 129 |
| 5, 191, 1, 188, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 43 x 5 x 191 x 1 x 188 x 3 = 3057207120
Therefore, the lowest common multiple of 660,764,946,752,387 is 3057207120.
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.
660 x 764 x 946 x 752 x 387 = 138821660904960
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
764 : 1, 2, 4, 191, 382, 764
946 : 1, 2, 11, 22, 43, 86, 473, 946
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,764,946,752,387, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
764:2x 2x 191
946:2x 11x 43
752:2x 2x 2x 2x 47
387:3x 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 2x 2x 3x 11x 43 = 45408
Therefore, the value for common factors is 45408.
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 = 138821660904960/(1x45408)
LCM = 138821660904960/45408
LCM = 3057207120
Thus, we can understand that the LCM of 660,764,946,752,387 is 3057207120.
