Find LCM of 945,671,644,670,913 with Prime Factorization
| 2 | 945, 671, 644, 670, 913 |
| 5 | 945, 671, 322, 335, 913 |
| 7 | 189, 671, 322, 67, 913 |
| 11 | 27, 671, 46, 67, 913 |
| 27, 61, 46, 67, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 27 x 61 x 46 x 67 x 83 = 324410611140
Therefore, the lowest common multiple of 945,671,644,670,913 is 324410611140.
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.
945 x 671 x 644 x 670 x 913 = 249796170577800
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
671 : 1, 11, 61, 671
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
670 : 1, 2, 5, 10, 67, 134, 335, 670
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,671,644,670,913, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
671:11x 61
644:2x 2x 7x 23
670:2x 5x 67
913:11x 83
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 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 249796170577800/(1x770)
LCM = 249796170577800/770
LCM = 324410611140
Thus, we can understand that the LCM of 945,671,644,670,913 is 324410611140.
