Given numbers are 391,871,841,736,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,871,841,736,667 is 9165177632.
Find LCM of 391,871,841,736,667 with Prime Factorization
| 23 | 391, 871, 841, 736, 667 |
| 29 | 17, 871, 841, 32, 29 |
| 17, 871, 1, 32, 29 |
Multiply the prime numbers at the bottom and the left side.
23 x 29 x 17 x 871 x 1 x 32 x 29 = 9165177632
Therefore, the lowest common multiple of 391,871,841,736,667 is 9165177632.
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.
391 x 871 x 841 x 736 x 667 = 140602990052512
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.
391 : 1, 17, 23, 391
871 : 1, 13, 67, 871
841 : 1, 29, 841
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,871,841,736,667, is 1.
Now, the common factors can be found like this.
391:17x 23
871:13x 67
841:29x 29
736:2x 2x 2x 2x 2x 23
667:23x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23x 29 = 15341
Therefore, the value for common factors is 15341.
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 = 140602990052512/(1x15341)
LCM = 140602990052512/15341
LCM = 9165177632
Thus, we can understand that the LCM of 391,871,841,736,667 is 9165177632.
