Given numbers are 694,855,630,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,855,630,705 is 195218730.
Find LCM of 694,855,630,705 with Prime Factorization
| 2 | 694, 855, 630, 705 |
| 3 | 347, 855, 315, 705 |
| 3 | 347, 285, 105, 235 |
| 5 | 347, 95, 35, 235 |
| 347, 19, 7, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 347 x 19 x 7 x 47 = 195218730
Therefore, the lowest common multiple of 694,855,630,705 is 195218730.
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.
694 x 855 x 630 x 705 = 263545285500
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.
694 : 1, 2, 347, 694
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,855,630,705, is 1.
Now, the common factors can be found like this.
694:2x 347
855:3x 3x 5x 19
630:2x 3x 3x 5x 7
705:3x 5x 47
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 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 263545285500/(1x1350)
LCM = 263545285500/1350
LCM = 195218730
Thus, we can understand that the LCM of 694,855,630,705 is 195218730.
