Given numbers are 631,292,623,146,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,292,623,146,871 is 99981215516.
Find LCM of 631,292,623,146,871 with Prime Factorization
| 2 | 631, 292, 623, 146, 871 |
| 73 | 631, 146, 623, 73, 871 |
| 631, 2, 623, 1, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 73 x 631 x 2 x 623 x 1 x 871 = 99981215516
Therefore, the lowest common multiple of 631,292,623,146,871 is 99981215516.
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.
631 x 292 x 623 x 146 x 871 = 14597257465336
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.
631 : 1, 631
292 : 1, 2, 4, 73, 146, 292
623 : 1, 7, 89, 623
146 : 1, 2, 73, 146
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,292,623,146,871, is 1.
Now, the common factors can be found like this.
631:631
292:2x 2x 73
623:7x 89
146:2x 73
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 73 = 146
Therefore, the value for common factors is 146.
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 = 14597257465336/(1x146)
LCM = 14597257465336/146
LCM = 99981215516
Thus, we can understand that the LCM of 631,292,623,146,871 is 99981215516.
