Given numbers are 340,931,494,498,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,931,494,498,689 is 54305918940.
Find LCM of 340,931,494,498,689 with Prime Factorization
| 2 | 340, 931, 494, 498, 689 |
| 13 | 170, 931, 247, 249, 689 |
| 19 | 170, 931, 19, 249, 53 |
| 170, 49, 1, 249, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 170 x 49 x 1 x 249 x 53 = 54305918940
Therefore, the lowest common multiple of 340,931,494,498,689 is 54305918940.
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.
340 x 931 x 494 x 498 x 689 = 53654247912720
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
931 : 1, 7, 19, 49, 133, 931
494 : 1, 2, 13, 19, 26, 38, 247, 494
498 : 1, 2, 3, 6, 83, 166, 249, 498
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,931,494,498,689, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
931:7x 7x 19
494:2x 13x 19
498:2x 3x 83
689:13x 53
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 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 53654247912720/(1x988)
LCM = 53654247912720/988
LCM = 54305918940
Thus, we can understand that the LCM of 340,931,494,498,689 is 54305918940.
