Given numbers are 914,685,492,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,685,492,420 is 1078126980.
Find LCM of 914,685,492,420 with Prime Factorization
| 2 | 914, 685, 492, 420 |
| 2 | 457, 685, 246, 210 |
| 3 | 457, 685, 123, 105 |
| 5 | 457, 685, 41, 35 |
| 457, 137, 41, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 457 x 137 x 41 x 7 = 1078126980
Therefore, the lowest common multiple of 914,685,492,420 is 1078126980.
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.
914 x 685 x 492 x 420 = 129375237600
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.
914 : 1, 2, 457, 914
685 : 1, 5, 137, 685
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 914,685,492,420, is 1.
Now, the common factors can be found like this.
914:2x 457
685:5x 137
492:2x 2x 3x 41
420:2x 2x 3x 5x 7
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 129375237600/(1x120)
LCM = 129375237600/120
LCM = 1078126980
Thus, we can understand that the LCM of 914,685,492,420 is 1078126980.
