Given numbers are 694,352,715,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,352,715,855 is 1357630560.
Find LCM of 694,352,715,855 with Prime Factorization
| 2 | 694, 352, 715, 855 |
| 5 | 347, 176, 715, 855 |
| 11 | 347, 176, 143, 171 |
| 347, 16, 13, 171 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 347 x 16 x 13 x 171 = 1357630560
Therefore, the lowest common multiple of 694,352,715,855 is 1357630560.
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.
694 x 352 x 715 x 855 = 149339361600
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.
694 : 1, 2, 347, 694
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
715 : 1, 5, 11, 13, 55, 65, 143, 715
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,352,715,855, is 1.
Now, the common factors can be found like this.
694:2x 347
352:2x 2x 2x 2x 2x 11
715:5x 11x 13
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 149339361600/(1x110)
LCM = 149339361600/110
LCM = 1357630560
Thus, we can understand that the LCM of 694,352,715,855 is 1357630560.
