Find LCM of 560,670,423,918,788 with Prime Factorization
| 2 | 560, 670, 423, 918, 788 |
| 2 | 280, 335, 423, 459, 394 |
| 3 | 140, 335, 423, 459, 197 |
| 3 | 140, 335, 141, 153, 197 |
| 5 | 140, 335, 47, 51, 197 |
| 28, 67, 47, 51, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 28 x 67 x 47 x 51 x 197 = 159455535120
Therefore, the lowest common multiple of 560,670,423,918,788 is 159455535120.
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.
560 x 670 x 423 x 918 x 788 = 114807985286400
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
670 : 1, 2, 5, 10, 67, 134, 335, 670
423 : 1, 3, 9, 47, 141, 423
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,670,423,918,788, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
670:2x 5x 67
423:3x 3x 47
918:2x 3x 3x 3x 17
788:2x 2x 197
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 114807985286400/(1x720)
LCM = 114807985286400/720
LCM = 159455535120
Thus, we can understand that the LCM of 560,670,423,918,788 is 159455535120.
