Find LCM of 991,664,448,664,491 with Prime Factorization
2 | 991, 664, 448, 664, 491 |
2 | 991, 332, 224, 332, 491 |
2 | 991, 166, 112, 166, 491 |
83 | 991, 83, 56, 83, 491 |
991, 1, 56, 1, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 83 x 991 x 1 x 56 x 1 x 491 = 18093027904
Therefore, the lowest common multiple of 991,664,448,664,491 is 18093027904.
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.
991 x 664 x 448 x 664 x 491 = 96110164226048
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.
991 : 1, 991
664 : 1, 2, 4, 8, 83, 166, 332, 664
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
664 : 1, 2, 4, 8, 83, 166, 332, 664
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,664,448,664,491, is 1.
Now, the common factors can be found like this.
991:991
664:2x 2x 2x 83
448:2x 2x 2x 2x 2x 2x 7
664:2x 2x 2x 83
491:491
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 2x 83 = 5312
Therefore, the value for common factors is 5312.
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 = 96110164226048/(1x5312)
LCM = 96110164226048/5312
LCM = 18093027904
Thus, we can understand that the LCM of 991,664,448,664,491 is 18093027904.
