The LCM of 646,495,704,923,220 is 9444726720.
Find LCM of 646,495,704,923,220 with Prime Factorization
| 2 | 646, 495, 704, 923, 220 |
| 2 | 323, 495, 352, 923, 110 |
| 5 | 323, 495, 176, 923, 55 |
| 11 | 323, 99, 176, 923, 11 |
| 323, 9, 16, 923, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 323 x 9 x 16 x 923 x 1 = 9444726720
Therefore, the lowest common multiple of 646,495,704,923,220 is 9444726720.
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.
646 x 495 x 704 x 923 x 220 = 45712477324800
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
923 : 1, 13, 71, 923
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,495,704,923,220, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
495:3x 3x 5x 11
704:2x 2x 2x 2x 2x 2x 11
923:13x 71
220:2x 2x 5x 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 2x 2x 5x 11x 11 = 4840
Therefore, the value for common factors is 4840.
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 = 45712477324800/(1x4840)
LCM = 45712477324800/4840
LCM = 9444726720
Thus, we can understand that the LCM of 646,495,704,923,220 is 9444726720.
