Find LCM of 165,414,780,616,438 with Prime Factorization
| 2 | 165, 414, 780, 616, 438 |
| 2 | 165, 207, 390, 308, 219 |
| 3 | 165, 207, 195, 154, 219 |
| 5 | 55, 69, 65, 154, 73 |
| 11 | 11, 69, 13, 154, 73 |
| 1, 69, 13, 14, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 1 x 69 x 13 x 14 x 73 = 605044440
Therefore, the lowest common multiple of 165,414,780,616,438 is 605044440.
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.
165 x 414 x 780 x 616 x 438 = 14375855894400
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,414,780,616,438, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
414:2x 3x 3x 23
780:2x 2x 3x 5x 13
616:2x 2x 2x 7x 11
438:2x 3x 73
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 3x 5x 11 = 23760
Therefore, the value for common factors is 23760.
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 = 14375855894400/(1x23760)
LCM = 14375855894400/23760
LCM = 605044440
Thus, we can understand that the LCM of 165,414,780,616,438 is 605044440.
