Given numbers are 121,630,874,726
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,630,874,726 is 33312510.
Find LCM of 121,630,874,726 with Prime Factorization
| 2 | 121, 630, 874, 726 |
| 3 | 121, 315, 437, 363 |
| 11 | 121, 105, 437, 121 |
| 11 | 11, 105, 437, 11 |
| 1, 105, 437, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 11 x 1 x 105 x 437 x 1 = 33312510
Therefore, the lowest common multiple of 121,630,874,726 is 33312510.
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.
121 x 630 x 874 x 726 = 48369764520
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.
121 : 1, 11, 121
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
874 : 1, 2, 19, 23, 38, 46, 437, 874
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,630,874,726, is 1.
Now, the common factors can be found like this.
121:11x 11
630:2x 3x 3x 5x 7
874:2x 19x 23
726:2x 3x 11x 11
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 3x 11x 11 = 1452
Therefore, the value for common factors is 1452.
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 = 48369764520/(1x1452)
LCM = 48369764520/1452
LCM = 33312510
Thus, we can understand that the LCM of 121,630,874,726 is 33312510.
