Given numbers are 480,700,238,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 480,700,238,385 is 3141600.
Find LCM of 480,700,238,385 with Prime Factorization
| 2 | 480, 700, 238, 385 |
| 2 | 240, 350, 119, 385 |
| 5 | 120, 175, 119, 385 |
| 7 | 24, 35, 119, 77 |
| 24, 5, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 24 x 5 x 17 x 11 = 3141600
Therefore, the lowest common multiple of 480,700,238,385 is 3141600.
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.
480 x 700 x 238 x 385 = 30787680000
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.
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
238 : 1, 2, 7, 14, 17, 34, 119, 238
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,700,238,385, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
700:2x 2x 5x 5x 7
238:2x 7x 17
385:5x 7x 11
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 5x 5x 7x 7 = 9800
Therefore, the value for common factors is 9800.
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 = 30787680000/(1x9800)
LCM = 30787680000/9800
LCM = 3141600
Thus, we can understand that the LCM of 480,700,238,385 is 3141600.
