Given numbers are 640,221,850,299
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,221,850,299 is 16265600.
Find LCM of 640,221,850,299 with Prime Factorization
| 2 | 640, 221, 850, 299 |
| 5 | 320, 221, 425, 299 |
| 13 | 64, 221, 85, 299 |
| 17 | 64, 17, 85, 23 |
| 64, 1, 5, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 17 x 64 x 1 x 5 x 23 = 16265600
Therefore, the lowest common multiple of 640,221,850,299 is 16265600.
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.
640 x 221 x 850 x 299 = 35946976000
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
221 : 1, 13, 17, 221
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,221,850,299, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
221:13x 17
850:2x 5x 5x 17
299:13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 17 = 2210
Therefore, the value for common factors is 2210.
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 = 35946976000/(1x2210)
LCM = 35946976000/2210
LCM = 16265600
Thus, we can understand that the LCM of 640,221,850,299 is 16265600.
