Given numbers are 722,715,363,521,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,715,363,521,649 is 523657001010.
Find LCM of 722,715,363,521,649 with Prime Factorization
| 11 | 722, 715, 363, 521, 649 |
| 722, 65, 33, 521, 59 |
Multiply the prime numbers at the bottom and the left side.
11 x 722 x 65 x 33 x 521 x 59 = 523657001010
Therefore, the lowest common multiple of 722,715,363,521,649 is 523657001010.
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.
722 x 715 x 363 x 521 x 649 = 63362497122210
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.
722 : 1, 2, 19, 38, 361, 722
715 : 1, 5, 11, 13, 55, 65, 143, 715
363 : 1, 3, 11, 33, 121, 363
521 : 1, 521
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,715,363,521,649, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
715:5x 11x 13
363:3x 11x 11
521:521
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 63362497122210/(1x121)
LCM = 63362497122210/121
LCM = 523657001010
Thus, we can understand that the LCM of 722,715,363,521,649 is 523657001010.
