Given numbers are 649,154,896,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,154,896,429 is 22678656.
Find LCM of 649,154,896,429 with Prime Factorization
| 2 | 649, 154, 896, 429 |
| 7 | 649, 77, 448, 429 |
| 11 | 649, 11, 64, 429 |
| 59, 1, 64, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 59 x 1 x 64 x 39 = 22678656
Therefore, the lowest common multiple of 649,154,896,429 is 22678656.
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.
649 x 154 x 896 x 429 = 38417643264
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.
649 : 1, 11, 59, 649
154 : 1, 2, 7, 11, 14, 22, 77, 154
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,154,896,429, is 1.
Now, the common factors can be found like this.
649:11x 59
154:2x 7x 11
896:2x 2x 2x 2x 2x 2x 2x 7
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 11 = 1694
Therefore, the value for common factors is 1694.
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 = 38417643264/(1x1694)
LCM = 38417643264/1694
LCM = 22678656
Thus, we can understand that the LCM of 649,154,896,429 is 22678656.
