Given numbers are 476,168,640,829
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,168,640,829 is 189409920.
Find LCM of 476,168,640,829 with Prime Factorization
| 2 | 476, 168, 640, 829 |
| 2 | 238, 84, 320, 829 |
| 2 | 119, 42, 160, 829 |
| 7 | 119, 21, 80, 829 |
| 17, 3, 80, 829 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 17 x 3 x 80 x 829 = 189409920
Therefore, the lowest common multiple of 476,168,640,829 is 189409920.
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.
476 x 168 x 640 x 829 = 42427822080
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,168,640,829, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
168:2x 2x 2x 3x 7
640:2x 2x 2x 2x 2x 2x 2x 5
829:829
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 7 = 224
Therefore, the value for common factors is 224.
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 = 42427822080/(1x224)
LCM = 42427822080/224
LCM = 189409920
Thus, we can understand that the LCM of 476,168,640,829 is 189409920.
