Given numbers are 464,154,657,643,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 464,154,657,643,680 is 1282932992880.
Find LCM of 464,154,657,643,680 with Prime Factorization
| 2 | 464, 154, 657, 643, 680 |
| 2 | 232, 77, 657, 643, 340 |
| 2 | 116, 77, 657, 643, 170 |
| 58, 77, 657, 643, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 58 x 77 x 657 x 643 x 85 = 1282932992880
Therefore, the lowest common multiple of 464,154,657,643,680 is 1282932992880.
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.
464 x 154 x 657 x 643 x 680 = 20526927886080
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.
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
154 : 1, 2, 7, 11, 14, 22, 77, 154
657 : 1, 3, 9, 73, 219, 657
643 : 1, 643
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 464,154,657,643,680, is 1.
Now, the common factors can be found like this.
464:2x 2x 2x 2x 29
154:2x 7x 11
657:3x 3x 73
643:643
680:2x 2x 2x 5x 17
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 2 = 16
Therefore, the value for common factors is 16.
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 = 20526927886080/(1x16)
LCM = 20526927886080/16
LCM = 1282932992880
Thus, we can understand that the LCM of 464,154,657,643,680 is 1282932992880.
