Given numbers are 689,774,249,357,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,774,249,357,441 is 36870860754.
Find LCM of 689,774,249,357,441 with Prime Factorization
| 3 | 689, 774, 249, 357, 441 |
| 3 | 689, 258, 83, 119, 147 |
| 7 | 689, 86, 83, 119, 49 |
| 689, 86, 83, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 689 x 86 x 83 x 17 x 7 = 36870860754
Therefore, the lowest common multiple of 689,774,249,357,441 is 36870860754.
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.
689 x 774 x 249 x 357 x 441 = 20905778047518
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.
689 : 1, 13, 53, 689
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
249 : 1, 3, 83, 249
357 : 1, 3, 7, 17, 21, 51, 119, 357
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,774,249,357,441, is 1.
Now, the common factors can be found like this.
689:13x 53
774:2x 3x 3x 43
249:3x 83
357:3x 7x 17
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 20905778047518/(1x567)
LCM = 20905778047518/567
LCM = 36870860754
Thus, we can understand that the LCM of 689,774,249,357,441 is 36870860754.
