Given numbers are 701,408,640,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,408,640,400 is 114403200.
Find LCM of 701,408,640,400 with Prime Factorization
| 2 | 701, 408, 640, 400 |
| 2 | 701, 204, 320, 200 |
| 2 | 701, 102, 160, 100 |
| 2 | 701, 51, 80, 50 |
| 5 | 701, 51, 40, 25 |
| 701, 51, 8, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 701 x 51 x 8 x 5 = 114403200
Therefore, the lowest common multiple of 701,408,640,400 is 114403200.
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.
701 x 408 x 640 x 400 = 73218048000
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.
701 : 1, 701
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,408,640,400, is 1.
Now, the common factors can be found like this.
701:701
408:2x 2x 2x 3x 17
640:2x 2x 2x 2x 2x 2x 2x 5
400:2x 2x 2x 2x 5x 5
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 2x 2x 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 73218048000/(1x640)
LCM = 73218048000/640
LCM = 114403200
Thus, we can understand that the LCM of 701,408,640,400 is 114403200.
