Given numbers are 121,697,145,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,697,145,902 is 24457730.
Find LCM of 121,697,145,902 with Prime Factorization
| 11 | 121, 697, 145, 902 |
| 41 | 11, 697, 145, 82 |
| 11, 17, 145, 2 |
Multiply the prime numbers at the bottom and the left side.
11 x 41 x 11 x 17 x 145 x 2 = 24457730
Therefore, the lowest common multiple of 121,697,145,902 is 24457730.
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 697 x 145 x 902 = 11030436230
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
697 : 1, 17, 41, 697
145 : 1, 5, 29, 145
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,697,145,902, is 1.
Now, the common factors can be found like this.
121:11x 11
697:17x 41
145:5x 29
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 41 = 451
Therefore, the value for common factors is 451.
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 = 11030436230/(1x451)
LCM = 11030436230/451
LCM = 24457730
Thus, we can understand that the LCM of 121,697,145,902 is 24457730.
