Find LCM of 805,209,342,420,716 with Prime Factorization
| 2 | 805, 209, 342, 420, 716 |
| 2 | 805, 209, 171, 210, 358 |
| 3 | 805, 209, 171, 105, 179 |
| 5 | 805, 209, 57, 35, 179 |
| 7 | 161, 209, 57, 7, 179 |
| 19 | 23, 209, 57, 1, 179 |
| 23, 11, 3, 1, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 19 x 23 x 11 x 3 x 1 x 179 = 1084170780
Therefore, the lowest common multiple of 805,209,342,420,716 is 1084170780.
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.
805 x 209 x 342 x 420 x 716 = 17303365648800
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
209 : 1, 11, 19, 209
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,209,342,420,716, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
209:11x 19
342:2x 3x 3x 19
420:2x 2x 3x 5x 7
716:2x 2x 179
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 3x 5x 7x 19 = 15960
Therefore, the value for common factors is 15960.
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 = 17303365648800/(1x15960)
LCM = 17303365648800/15960
LCM = 1084170780
Thus, we can understand that the LCM of 805,209,342,420,716 is 1084170780.
