Given numbers are 185,407,374,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,407,374,643 is 44489170.
Find LCM of 185,407,374,643 with Prime Factorization
| 11 | 185, 407, 374, 643 |
| 37 | 185, 37, 34, 643 |
| 5, 1, 34, 643 |
Multiply the prime numbers at the bottom and the left side.
11 x 37 x 5 x 1 x 34 x 643 = 44489170
Therefore, the lowest common multiple of 185,407,374,643 is 44489170.
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.
185 x 407 x 374 x 643 = 18107092190
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.
185 : 1, 5, 37, 185
407 : 1, 11, 37, 407
374 : 1, 2, 11, 17, 22, 34, 187, 374
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,407,374,643, is 1.
Now, the common factors can be found like this.
185:5x 37
407:11x 37
374:2x 11x 17
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 37 = 407
Therefore, the value for common factors is 407.
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 = 18107092190/(1x407)
LCM = 18107092190/407
LCM = 44489170
Thus, we can understand that the LCM of 185,407,374,643 is 44489170.
