Given numbers are 824,476,678,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,476,678,946 is 15722985432.
Find LCM of 824,476,678,946 with Prime Factorization
| 2 | 824, 476, 678, 946 |
| 2 | 412, 238, 339, 473 |
| 206, 119, 339, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 206 x 119 x 339 x 473 = 15722985432
Therefore, the lowest common multiple of 824,476,678,946 is 15722985432.
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.
824 x 476 x 678 x 946 = 251567766912
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
678 : 1, 2, 3, 6, 113, 226, 339, 678
946 : 1, 2, 11, 22, 43, 86, 473, 946
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,476,678,946, is 2.
Now, the common factors can be found like this.
824:2x 2x 2x 103
476:2x 2x 7x 17
678:2x 3x 113
946:2x 11x 43
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 2 = 8
Therefore, the value for common factors is 8.
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 = 251567766912/(2x8)
LCM = 251567766912/16
LCM = 15722985432
Thus, we can understand that the LCM of 824,476,678,946 is 15722985432.
