Given numbers are 654,840,705,425,269
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,840,705,425,269 is 98395411800.
Find LCM of 654,840,705,425,269 with Prime Factorization
| 2 | 654, 840, 705, 425, 269 |
| 3 | 327, 420, 705, 425, 269 |
| 5 | 109, 140, 235, 425, 269 |
| 109, 28, 47, 85, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 109 x 28 x 47 x 85 x 269 = 98395411800
Therefore, the lowest common multiple of 654,840,705,425,269 is 98395411800.
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.
654 x 840 x 705 x 425 x 269 = 44277935310000
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
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
705 : 1, 3, 5, 15, 47, 141, 235, 705
425 : 1, 5, 17, 25, 85, 425
269 : 1, 269
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,840,705,425,269, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
840:2x 2x 2x 3x 5x 7
705:3x 5x 47
425:5x 5x 17
269:269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 44277935310000/(1x450)
LCM = 44277935310000/450
LCM = 98395411800
Thus, we can understand that the LCM of 654,840,705,425,269 is 98395411800.
