Given numbers are 902,724,721,387,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,724,721,387,164 is 91109012148.
Find LCM of 902,724,721,387,164 with Prime Factorization
| 2 | 902, 724, 721, 387, 164 |
| 2 | 451, 362, 721, 387, 82 |
| 41 | 451, 181, 721, 387, 41 |
| 11, 181, 721, 387, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 11 x 181 x 721 x 387 x 1 = 91109012148
Therefore, the lowest common multiple of 902,724,721,387,164 is 91109012148.
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.
902 x 724 x 721 x 387 x 164 = 29883755984544
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
724 : 1, 2, 4, 181, 362, 724
721 : 1, 7, 103, 721
387 : 1, 3, 9, 43, 129, 387
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,724,721,387,164, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
724:2x 2x 181
721:7x 103
387:3x 3x 43
164:2x 2x 41
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 2x 41 = 328
Therefore, the value for common factors is 328.
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 = 29883755984544/(1x328)
LCM = 29883755984544/328
LCM = 91109012148
Thus, we can understand that the LCM of 902,724,721,387,164 is 91109012148.
