Given numbers are 672,290,210,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,290,210,909 is 29524320.
Find LCM of 672,290,210,909 with Prime Factorization
| 2 | 672, 290, 210, 909 |
| 3 | 336, 145, 105, 909 |
| 5 | 112, 145, 35, 303 |
| 7 | 112, 29, 7, 303 |
| 16, 29, 1, 303 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 16 x 29 x 1 x 303 = 29524320
Therefore, the lowest common multiple of 672,290,210,909 is 29524320.
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.
672 x 290 x 210 x 909 = 37200643200
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
290 : 1, 2, 5, 10, 29, 58, 145, 290
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,290,210,909, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
290:2x 5x 29
210:2x 3x 5x 7
909:3x 3x 101
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 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 37200643200/(1x1260)
LCM = 37200643200/1260
LCM = 29524320
Thus, we can understand that the LCM of 672,290,210,909 is 29524320.
