Given numbers are 146,780,391,875,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,780,391,875,923 is 276624484500.
Find LCM of 146,780,391,875,923 with Prime Factorization
| 2 | 146, 780, 391, 875, 923 |
| 5 | 73, 390, 391, 875, 923 |
| 13 | 73, 78, 391, 175, 923 |
| 73, 6, 391, 175, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 73 x 6 x 391 x 175 x 71 = 276624484500
Therefore, the lowest common multiple of 146,780,391,875,923 is 276624484500.
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.
146 x 780 x 391 x 875 x 923 = 35961182985000
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.
146 : 1, 2, 73, 146
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
391 : 1, 17, 23, 391
875 : 1, 5, 7, 25, 35, 125, 175, 875
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,780,391,875,923, is 1.
Now, the common factors can be found like this.
146:2x 73
780:2x 2x 3x 5x 13
391:17x 23
875:5x 5x 5x 7
923:13x 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 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 35961182985000/(1x130)
LCM = 35961182985000/130
LCM = 276624484500
Thus, we can understand that the LCM of 146,780,391,875,923 is 276624484500.
