Given numbers are 784,943,299,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,943,299,922 is 4430696816.
Find LCM of 784,943,299,922 with Prime Factorization
| 2 | 784, 943, 299, 922 |
| 23 | 392, 943, 299, 461 |
| 392, 41, 13, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 392 x 41 x 13 x 461 = 4430696816
Therefore, the lowest common multiple of 784,943,299,922 is 4430696816.
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.
784 x 943 x 299 x 922 = 203812053536
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
943 : 1, 23, 41, 943
299 : 1, 13, 23, 299
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,943,299,922, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
943:23x 41
299:13x 23
922:2x 461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23 = 46
Therefore, the value for common factors is 46.
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 = 203812053536/(1x46)
LCM = 203812053536/46
LCM = 4430696816
Thus, we can understand that the LCM of 784,943,299,922 is 4430696816.
