Find LCM of 520,158,678,440,918 with Prime Factorization
| 2 | 520, 158, 678, 440, 918 |
| 2 | 260, 79, 339, 220, 459 |
| 2 | 130, 79, 339, 110, 459 |
| 3 | 65, 79, 339, 55, 459 |
| 5 | 65, 79, 113, 55, 153 |
| 13, 79, 113, 11, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 79 x 113 x 11 x 153 = 23437659960
Therefore, the lowest common multiple of 520,158,678,440,918 is 23437659960.
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.
520 x 158 x 678 x 440 x 918 = 22500153561600
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
158 : 1, 2, 79, 158
678 : 1, 2, 3, 6, 113, 226, 339, 678
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,158,678,440,918, is 2.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
158:2x 79
678:2x 3x 113
440:2x 2x 2x 5x 11
918:2x 3x 3x 3x 17
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 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 22500153561600/(2x480)
LCM = 22500153561600/960
LCM = 23437659960
Thus, we can understand that the LCM of 520,158,678,440,918 is 23437659960.
