Given numbers are 689,926,782,420,267
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,926,782,420,267 is 4662472329060.
Find LCM of 689,926,782,420,267 with Prime Factorization
| 2 | 689, 926, 782, 420, 267 |
| 3 | 689, 463, 391, 210, 267 |
| 689, 463, 391, 70, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 689 x 463 x 391 x 70 x 89 = 4662472329060
Therefore, the lowest common multiple of 689,926,782,420,267 is 4662472329060.
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.
689 x 926 x 782 x 420 x 267 = 55949667948720
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.
689 : 1, 13, 53, 689
926 : 1, 2, 463, 926
782 : 1, 2, 17, 23, 34, 46, 391, 782
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
267 : 1, 3, 89, 267
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,926,782,420,267, is 1.
Now, the common factors can be found like this.
689:13x 53
926:2x 463
782:2x 17x 23
420:2x 2x 3x 5x 7
267:3x 89
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 3 = 12
Therefore, the value for common factors is 12.
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 = 55949667948720/(1x12)
LCM = 55949667948720/12
LCM = 4662472329060
Thus, we can understand that the LCM of 689,926,782,420,267 is 4662472329060.
