The LCM of 618,564,432,768 is 33460992.
Find LCM of 618,564,432,768 with Prime Factorization
| 2 | 618, 564, 432, 768 |
| 2 | 309, 282, 216, 384 |
| 2 | 309, 141, 108, 192 |
| 2 | 309, 141, 54, 96 |
| 3 | 309, 141, 27, 48 |
| 103, 47, 9, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 103 x 47 x 9 x 16 = 33460992
Therefore, the lowest common multiple of 618,564,432,768 is 33460992.
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.
618 x 564 x 432 x 768 = 115641188352
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,564,432,768, is 6.
Now, the common factors can be found like this.
618:2x 3x 103
564:2x 2x 3x 47
432:2x 2x 2x 2x 3x 3x 3
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 115641188352/(6x576)
LCM = 115641188352/3456
LCM = 33460992
Thus, we can understand that the LCM of 618,564,432,768 is 33460992.
