Given numbers are 422,840,545,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,840,545,436 is 19319160.
Find LCM of 422,840,545,436 with Prime Factorization
| 2 | 422, 840, 545, 436 |
| 2 | 211, 420, 545, 218 |
| 5 | 211, 210, 545, 109 |
| 109 | 211, 42, 109, 109 |
| 211, 42, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 109 x 211 x 42 x 1 x 1 = 19319160
Therefore, the lowest common multiple of 422,840,545,436 is 19319160.
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.
422 x 840 x 545 x 436 = 84231537600
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.
422 : 1, 2, 211, 422
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
545 : 1, 5, 109, 545
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,840,545,436, is 1.
Now, the common factors can be found like this.
422:2x 211
840:2x 2x 2x 3x 5x 7
545:5x 109
436:2x 2x 109
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 5x 109 = 4360
Therefore, the value for common factors is 4360.
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 = 84231537600/(1x4360)
LCM = 84231537600/4360
LCM = 19319160
Thus, we can understand that the LCM of 422,840,545,436 is 19319160.
