The LCM of 744,144,561,440 is 4173840.
Find LCM of 744,144,561,440 with Prime Factorization
| 2 | 744, 144, 561, 440 |
| 2 | 372, 72, 561, 220 |
| 2 | 186, 36, 561, 110 |
| 3 | 93, 18, 561, 55 |
| 11 | 31, 6, 187, 55 |
| 31, 6, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 31 x 6 x 17 x 5 = 4173840
Therefore, the lowest common multiple of 744,144,561,440 is 4173840.
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.
744 x 144 x 561 x 440 = 26445450240
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.
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
561 : 1, 3, 11, 17, 33, 51, 187, 561
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 744,144,561,440, is 1.
Now, the common factors can be found like this.
744:2x 2x 2x 3x 31
144:2x 2x 2x 2x 3x 3
561:3x 11x 17
440:2x 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 2x 2x 2x 3x 3x 11 = 6336
Therefore, the value for common factors is 6336.
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 = 26445450240/(1x6336)
LCM = 26445450240/6336
LCM = 4173840
Thus, we can understand that the LCM of 744,144,561,440 is 4173840.
