Given numbers are 695,249,458,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 695,249,458,819 is 21637758870.
Find LCM of 695,249,458,819 with Prime Factorization
| 3 | 695, 249, 458, 819 |
| 695, 83, 458, 273 |
Multiply the prime numbers at the bottom and the left side.
3 x 695 x 83 x 458 x 273 = 21637758870
Therefore, the lowest common multiple of 695,249,458,819 is 21637758870.
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.
695 x 249 x 458 x 819 = 64913276610
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.
695 : 1, 5, 139, 695
249 : 1, 3, 83, 249
458 : 1, 2, 229, 458
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,249,458,819, is 1.
Now, the common factors can be found like this.
695:5x 139
249:3x 83
458:2x 229
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 64913276610/(1x3)
LCM = 64913276610/3
LCM = 21637758870
Thus, we can understand that the LCM of 695,249,458,819 is 21637758870.
