Find LCM of 437,828,580,355 with Prime Factorization
| 2 | 437, 828, 580, 355 |
| 2 | 437, 414, 290, 355 |
| 5 | 437, 207, 145, 355 |
| 23 | 437, 207, 29, 71 |
| 19, 9, 29, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 19 x 9 x 29 x 71 = 161960940
Therefore, the lowest common multiple of 437,828,580,355 is 161960940.
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.
437 x 828 x 580 x 355 = 74502032400
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.
437 : 1, 19, 23, 437
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,828,580,355, is 1.
Now, the common factors can be found like this.
437:19x 23
828:2x 2x 3x 3x 23
580:2x 2x 5x 29
355:5x 71
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 74502032400/(1x460)
LCM = 74502032400/460
LCM = 161960940
Thus, we can understand that the LCM of 437,828,580,355 is 161960940.
