Given numbers are 153,969,676,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,969,676,840 is 137559240.
Find LCM of 153,969,676,840 with Prime Factorization
| 2 | 153, 969, 676, 840 |
| 2 | 153, 969, 338, 420 |
| 3 | 153, 969, 169, 210 |
| 17 | 51, 323, 169, 70 |
| 3, 19, 169, 70 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 3 x 19 x 169 x 70 = 137559240
Therefore, the lowest common multiple of 153,969,676,840 is 137559240.
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.
153 x 969 x 676 x 840 = 84186254880
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.
153 : 1, 3, 9, 17, 51, 153
969 : 1, 3, 17, 19, 51, 57, 323, 969
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,969,676,840, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
969:3x 17x 19
676:2x 2x 13x 13
840:2x 2x 2x 3x 5x 7
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 84186254880/(1x612)
LCM = 84186254880/612
LCM = 137559240
Thus, we can understand that the LCM of 153,969,676,840 is 137559240.
