Find LCM of 462,440,875,688 with Prime Factorization
| 2 | 462, 440, 875, 688 |
| 2 | 231, 220, 875, 344 |
| 2 | 231, 110, 875, 172 |
| 5 | 231, 55, 875, 86 |
| 7 | 231, 11, 175, 86 |
| 11 | 33, 11, 25, 86 |
| 3, 1, 25, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 11 x 3 x 1 x 25 x 86 = 19866000
Therefore, the lowest common multiple of 462,440,875,688 is 19866000.
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.
462 x 440 x 875 x 688 = 122374560000
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
875 : 1, 5, 7, 25, 35, 125, 175, 875
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,440,875,688, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
440:2x 2x 2x 5x 11
875:5x 5x 5x 7
688:2x 2x 2x 2x 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 5x 7x 11 = 6160
Therefore, the value for common factors is 6160.
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 = 122374560000/(1x6160)
LCM = 122374560000/6160
LCM = 19866000
Thus, we can understand that the LCM of 462,440,875,688 is 19866000.
