Given numbers are 671,705,760,661,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,705,760,661,418 is 47528781960.
Find LCM of 671,705,760,661,418 with Prime Factorization
| 2 | 671, 705, 760, 661, 418 |
| 5 | 671, 705, 380, 661, 209 |
| 11 | 671, 141, 76, 661, 209 |
| 19 | 61, 141, 76, 661, 19 |
| 61, 141, 4, 661, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 19 x 61 x 141 x 4 x 661 x 1 = 47528781960
Therefore, the lowest common multiple of 671,705,760,661,418 is 47528781960.
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.
671 x 705 x 760 x 661 x 418 = 99335154296400
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.
671 : 1, 11, 61, 671
705 : 1, 3, 5, 15, 47, 141, 235, 705
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
661 : 1, 661
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,705,760,661,418, is 1.
Now, the common factors can be found like this.
671:11x 61
705:3x 5x 47
760:2x 2x 2x 5x 19
661:661
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 19 = 2090
Therefore, the value for common factors is 2090.
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 = 99335154296400/(1x2090)
LCM = 99335154296400/2090
LCM = 47528781960
Thus, we can understand that the LCM of 671,705,760,661,418 is 47528781960.
