Given numbers are 637,715,887,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,715,887,462 is 186456270.
Find LCM of 637,715,887,462 with Prime Factorization
| 7 | 637, 715, 887, 462 |
| 11 | 91, 715, 887, 66 |
| 13 | 91, 65, 887, 6 |
| 7, 5, 887, 6 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 13 x 7 x 5 x 887 x 6 = 186456270
Therefore, the lowest common multiple of 637,715,887,462 is 186456270.
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.
637 x 715 x 887 x 462 = 186642726270
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.
637 : 1, 7, 13, 49, 91, 637
715 : 1, 5, 11, 13, 55, 65, 143, 715
887 : 1, 887
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,715,887,462, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
715:5x 11x 13
887:887
462:2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 13 = 1001
Therefore, the value for common factors is 1001.
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 = 186642726270/(1x1001)
LCM = 186642726270/1001
LCM = 186456270
Thus, we can understand that the LCM of 637,715,887,462 is 186456270.
