The LCM of 869,991,784,381,444 is 9517791644592.
Find LCM of 869,991,784,381,444 with Prime Factorization
| 2 | 869, 991, 784, 381, 444 |
| 2 | 869, 991, 392, 381, 222 |
| 3 | 869, 991, 196, 381, 111 |
| 869, 991, 196, 127, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 869 x 991 x 196 x 127 x 37 = 9517791644592
Therefore, the lowest common multiple of 869,991,784,381,444 is 9517791644592.
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.
869 x 991 x 784 x 381 x 444 = 114213499735104
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.
869 : 1, 11, 79, 869
991 : 1, 991
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
381 : 1, 3, 127, 381
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,991,784,381,444, is 1.
Now, the common factors can be found like this.
869:11x 79
991:991
784:2x 2x 2x 2x 7x 7
381:3x 127
444:2x 2x 3x 37
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 3 = 12
Therefore, the value for common factors is 12.
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 = 114213499735104/(1x12)
LCM = 114213499735104/12
LCM = 9517791644592
Thus, we can understand that the LCM of 869,991,784,381,444 is 9517791644592.
