Given numbers are 690,418,781,110
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,418,781,110 is 10238910.
Find LCM of 690,418,781,110 with Prime Factorization
| 2 | 690, 418, 781, 110 |
| 5 | 345, 209, 781, 55 |
| 11 | 69, 209, 781, 11 |
| 69, 19, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 69 x 19 x 71 x 1 = 10238910
Therefore, the lowest common multiple of 690,418,781,110 is 10238910.
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.
690 x 418 x 781 x 110 = 24778162200
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
418 : 1, 2, 11, 19, 22, 38, 209, 418
781 : 1, 11, 71, 781
110 : 1, 2, 5, 10, 11, 22, 55, 110
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,418,781,110, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
418:2x 11x 19
781:11x 71
110:2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 11x 11 = 2420
Therefore, the value for common factors is 2420.
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 = 24778162200/(1x2420)
LCM = 24778162200/2420
LCM = 10238910
Thus, we can understand that the LCM of 690,418,781,110 is 10238910.
