Given numbers are 471,708,638,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,708,638,288 is 851010336.
Find LCM of 471,708,638,288 with Prime Factorization
| 2 | 471, 708, 638, 288 |
| 2 | 471, 354, 319, 144 |
| 3 | 471, 177, 319, 72 |
| 157, 59, 319, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 157 x 59 x 319 x 24 = 851010336
Therefore, the lowest common multiple of 471,708,638,288 is 851010336.
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.
471 x 708 x 638 x 288 = 61272744192
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.
471 : 1, 3, 157, 471
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
638 : 1, 2, 11, 22, 29, 58, 319, 638
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,708,638,288, is 1.
Now, the common factors can be found like this.
471:3x 157
708:2x 2x 3x 59
638:2x 11x 29
288:2x 2x 2x 2x 2x 3x 3
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 61272744192/(1x72)
LCM = 61272744192/72
LCM = 851010336
Thus, we can understand that the LCM of 471,708,638,288 is 851010336.
