Given numbers are 427,840,446,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,840,446,164 is 468487320.
Find LCM of 427,840,446,164 with Prime Factorization
| 2 | 427, 840, 446, 164 |
| 2 | 427, 420, 223, 82 |
| 7 | 427, 210, 223, 41 |
| 61, 30, 223, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 61 x 30 x 223 x 41 = 468487320
Therefore, the lowest common multiple of 427,840,446,164 is 468487320.
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.
427 x 840 x 446 x 164 = 26235289920
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.
427 : 1, 7, 61, 427
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
446 : 1, 2, 223, 446
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,840,446,164, is 1.
Now, the common factors can be found like this.
427:7x 61
840:2x 2x 2x 3x 5x 7
446:2x 223
164:2x 2x 41
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 7 = 56
Therefore, the value for common factors is 56.
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 = 26235289920/(1x56)
LCM = 26235289920/56
LCM = 468487320
Thus, we can understand that the LCM of 427,840,446,164 is 468487320.
