Given numbers are 403,143,821,528
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,143,821,528 is 174695664.
Find LCM of 403,143,821,528 with Prime Factorization
| 11 | 403, 143, 821, 528 |
| 13 | 403, 13, 821, 48 |
| 31, 1, 821, 48 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 31 x 1 x 821 x 48 = 174695664
Therefore, the lowest common multiple of 403,143,821,528 is 174695664.
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.
403 x 143 x 821 x 528 = 24981479952
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.
403 : 1, 13, 31, 403
143 : 1, 11, 13, 143
821 : 1, 821
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,143,821,528, is 1.
Now, the common factors can be found like this.
403:13x 31
143:11x 13
821:821
528:2x 2x 2x 2x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 24981479952/(1x143)
LCM = 24981479952/143
LCM = 174695664
Thus, we can understand that the LCM of 403,143,821,528 is 174695664.
