The LCM of 359,639,856,680,642 is 16691216760.
Find LCM of 359,639,856,680,642 with Prime Factorization
| 2 | 359, 639, 856, 680, 642 |
| 2 | 359, 639, 428, 340, 321 |
| 2 | 359, 639, 214, 170, 321 |
| 3 | 359, 639, 107, 85, 321 |
| 107 | 359, 213, 107, 85, 107 |
| 359, 213, 1, 85, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 107 x 359 x 213 x 1 x 85 x 1 = 16691216760
Therefore, the lowest common multiple of 359,639,856,680,642 is 16691216760.
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.
359 x 639 x 856 x 680 x 642 = 85726089279360
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.
359 : 1, 359
639 : 1, 3, 9, 71, 213, 639
856 : 1, 2, 4, 8, 107, 214, 428, 856
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 359,639,856,680,642, is 1.
Now, the common factors can be found like this.
359:359
639:3x 3x 71
856:2x 2x 2x 107
680:2x 2x 2x 5x 17
642:2x 3x 107
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 2x 2x 3x 107 = 5136
Therefore, the value for common factors is 5136.
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 = 85726089279360/(1x5136)
LCM = 85726089279360/5136
LCM = 16691216760
Thus, we can understand that the LCM of 359,639,856,680,642 is 16691216760.
