Given numbers are 784,772,849,173,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,772,849,173,242 is 2689134567504.
Find LCM of 784,772,849,173,242 with Prime Factorization
| 2 | 784, 772, 849, 173, 242 |
| 2 | 392, 386, 849, 173, 121 |
| 196, 193, 849, 173, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 196 x 193 x 849 x 173 x 121 = 2689134567504
Therefore, the lowest common multiple of 784,772,849,173,242 is 2689134567504.
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 772 x 849 x 173 x 242 = 21513076540032
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
772 : 1, 2, 4, 193, 386, 772
849 : 1, 3, 283, 849
173 : 1, 173
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,772,849,173,242, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
772:2x 2x 193
849:3x 283
173:173
242:2x 11x 11
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 2 = 8
Therefore, the value for common factors is 8.
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 = 21513076540032/(1x8)
LCM = 21513076540032/8
LCM = 2689134567504
Thus, we can understand that the LCM of 784,772,849,173,242 is 2689134567504.
