Given numbers are 473,143,917,661,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,143,917,661,645 is 55907046195.
Find LCM of 473,143,917,661,645 with Prime Factorization
| 11 | 473, 143, 917, 661, 645 |
| 43 | 43, 13, 917, 661, 645 |
| 1, 13, 917, 661, 15 |
Multiply the prime numbers at the bottom and the left side.
11 x 43 x 1 x 13 x 917 x 661 x 15 = 55907046195
Therefore, the lowest common multiple of 473,143,917,661,645 is 55907046195.
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.
473 x 143 x 917 x 661 x 645 = 26444032850235
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.
473 : 1, 11, 43, 473
143 : 1, 11, 13, 143
917 : 1, 7, 131, 917
661 : 1, 661
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,143,917,661,645, is 1.
Now, the common factors can be found like this.
473:11x 43
143:11x 13
917:7x 131
661:661
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 43 = 473
Therefore, the value for common factors is 473.
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 = 26444032850235/(1x473)
LCM = 26444032850235/473
LCM = 55907046195
Thus, we can understand that the LCM of 473,143,917,661,645 is 55907046195.
