Find LCM of 440,936,715,988 with Prime Factorization
| 2 | 440, 936, 715, 988 |
| 2 | 220, 468, 715, 494 |
| 2 | 110, 234, 715, 247 |
| 5 | 55, 117, 715, 247 |
| 11 | 11, 117, 143, 247 |
| 13 | 1, 117, 13, 247 |
| 1, 9, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 13 x 1 x 9 x 1 x 19 = 978120
Therefore, the lowest common multiple of 440,936,715,988 is 978120.
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.
440 x 936 x 715 x 988 = 290932012800
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
715 : 1, 5, 11, 13, 55, 65, 143, 715
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,936,715,988, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
936:2x 2x 2x 3x 3x 13
715:5x 11x 13
988:2x 2x 13x 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 2x 2x 2x 2x 5x 11x 13x 13 = 297440
Therefore, the value for common factors is 297440.
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 = 290932012800/(1x297440)
LCM = 290932012800/297440
LCM = 978120
Thus, we can understand that the LCM of 440,936,715,988 is 978120.
