Find LCM of 688,240,726,576,246 with Prime Factorization
| 2 | 688, 240, 726, 576, 246 |
| 2 | 344, 120, 363, 288, 123 |
| 2 | 172, 60, 363, 144, 123 |
| 2 | 86, 30, 363, 72, 123 |
| 3 | 43, 15, 363, 36, 123 |
| 43, 5, 121, 12, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 43 x 5 x 121 x 12 x 41 = 614370240
Therefore, the lowest common multiple of 688,240,726,576,246 is 614370240.
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.
688 x 240 x 726 x 576 x 246 = 16986108395520
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
246 : 1, 2, 3, 6, 41, 82, 123, 246
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,240,726,576,246, is 2.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
240:2x 2x 2x 2x 3x 5
726:2x 3x 11x 11
576:2x 2x 2x 2x 2x 2x 3x 3
246:2x 3x 41
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 2x 2x 2x 3x 3x 3 = 13824
Therefore, the value for common factors is 13824.
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 = 16986108395520/(2x13824)
LCM = 16986108395520/27648
LCM = 614370240
Thus, we can understand that the LCM of 688,240,726,576,246 is 614370240.
