Given numbers are 671,451,732,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,451,732,770 is 11554620.
Find LCM of 671,451,732,770 with Prime Factorization
| 2 | 671, 451, 732, 770 |
| 11 | 671, 451, 366, 385 |
| 61 | 61, 41, 366, 35 |
| 1, 41, 6, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 61 x 1 x 41 x 6 x 35 = 11554620
Therefore, the lowest common multiple of 671,451,732,770 is 11554620.
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 451 x 732 x 770 = 170569300440
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
451 : 1, 11, 41, 451
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,451,732,770, is 1.
Now, the common factors can be found like this.
671:11x 61
451:11x 41
732:2x 2x 3x 61
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 61 = 14762
Therefore, the value for common factors is 14762.
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 = 170569300440/(1x14762)
LCM = 170569300440/14762
LCM = 11554620
Thus, we can understand that the LCM of 671,451,732,770 is 11554620.
