Given numbers are 219,105,487,630,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,105,487,630,689 is 15431622570.
Find LCM of 219,105,487,630,689 with Prime Factorization
| 3 | 219, 105, 487, 630, 689 |
| 5 | 73, 35, 487, 210, 689 |
| 7 | 73, 7, 487, 42, 689 |
| 73, 1, 487, 6, 689 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 73 x 1 x 487 x 6 x 689 = 15431622570
Therefore, the lowest common multiple of 219,105,487,630,689 is 15431622570.
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.
219 x 105 x 487 x 630 x 689 = 4860961109550
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.
219 : 1, 3, 73, 219
105 : 1, 3, 5, 7, 15, 21, 35, 105
487 : 1, 487
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,105,487,630,689, is 1.
Now, the common factors can be found like this.
219:3x 73
105:3x 5x 7
487:487
630:2x 3x 3x 5x 7
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.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 4860961109550/(1x315)
LCM = 4860961109550/315
LCM = 15431622570
Thus, we can understand that the LCM of 219,105,487,630,689 is 15431622570.
