Given numbers are 169,432,780,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,432,780,210 is 2555280.
Find LCM of 169,432,780,210 with Prime Factorization
| 2 | 169, 432, 780, 210 |
| 2 | 169, 216, 390, 105 |
| 3 | 169, 108, 195, 105 |
| 5 | 169, 36, 65, 35 |
| 13 | 169, 36, 13, 7 |
| 1, 36, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 36 x 13 x 7 = 2555280
Therefore, the lowest common multiple of 169,432,780,210 is 2555280.
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.
169 x 432 x 780 x 210 = 11958710400
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.
169 : 1, 13, 169
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,432,780,210, is 1.
Now, the common factors can be found like this.
169:13x 13
432:2x 2x 2x 2x 3x 3x 3
780:2x 2x 3x 5x 13
210:2x 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 2x 3x 3x 5x 13 = 4680
Therefore, the value for common factors is 4680.
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 = 11958710400/(1x4680)
LCM = 11958710400/4680
LCM = 2555280
Thus, we can understand that the LCM of 169,432,780,210 is 2555280.
