Given numbers are 840,999,147,654,626
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,999,147,654,626 is 66802450680.
Find LCM of 840,999,147,654,626 with Prime Factorization
| 2 | 840, 999, 147, 654, 626 |
| 3 | 420, 999, 147, 327, 313 |
| 7 | 140, 333, 49, 109, 313 |
| 20, 333, 7, 109, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 20 x 333 x 7 x 109 x 313 = 66802450680
Therefore, the lowest common multiple of 840,999,147,654,626 is 66802450680.
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.
840 x 999 x 147 x 654 x 626 = 50502652714080
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.
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
999 : 1, 3, 9, 27, 37, 111, 333, 999
147 : 1, 3, 7, 21, 49, 147
654 : 1, 2, 3, 6, 109, 218, 327, 654
626 : 1, 2, 313, 626
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,999,147,654,626, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
999:3x 3x 3x 37
147:3x 7x 7
654:2x 3x 109
626:2x 313
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 50502652714080/(1x756)
LCM = 50502652714080/756
LCM = 66802450680
Thus, we can understand that the LCM of 840,999,147,654,626 is 66802450680.
