Find LCM of 403,784,109,531,981 with Prime Factorization
3 | 403, 784, 109, 531, 981 |
3 | 403, 784, 109, 177, 327 |
109 | 403, 784, 109, 59, 109 |
403, 784, 1, 59, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 109 x 403 x 784 x 1 x 59 x 1 = 18286985808
Therefore, the lowest common multiple of 403,784,109,531,981 is 18286985808.
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 784 x 109 x 531 x 981 = 17939533077648
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
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
109 : 1, 109
531 : 1, 3, 9, 59, 177, 531
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,784,109,531,981, is 1.
Now, the common factors can be found like this.
403:13x 31
784:2x 2x 2x 2x 7x 7
109:109
531:3x 3x 59
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 109 = 981
Therefore, the value for common factors is 981.
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 = 17939533077648/(1x981)
LCM = 17939533077648/981
LCM = 18286985808
Thus, we can understand that the LCM of 403,784,109,531,981 is 18286985808.
