Given numbers are 231,487,874,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,487,874,636 is 10422172068.
Find LCM of 231,487,874,636 with Prime Factorization
| 2 | 231, 487, 874, 636 |
| 3 | 231, 487, 437, 318 |
| 77, 487, 437, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 77 x 487 x 437 x 106 = 10422172068
Therefore, the lowest common multiple of 231,487,874,636 is 10422172068.
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.
231 x 487 x 874 x 636 = 62533032408
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
487 : 1, 487
874 : 1, 2, 19, 23, 38, 46, 437, 874
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,487,874,636, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
487:487
874:2x 19x 23
636:2x 2x 3x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 62533032408/(1x6)
LCM = 62533032408/6
LCM = 10422172068
Thus, we can understand that the LCM of 231,487,874,636 is 10422172068.
