Given numbers are 612,794,630,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,794,630,820 is 348653340.
Find LCM of 612,794,630,820 with Prime Factorization
| 2 | 612, 794, 630, 820 |
| 2 | 306, 397, 315, 410 |
| 3 | 153, 397, 315, 205 |
| 3 | 51, 397, 105, 205 |
| 5 | 17, 397, 35, 205 |
| 17, 397, 7, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 17 x 397 x 7 x 41 = 348653340
Therefore, the lowest common multiple of 612,794,630,820 is 348653340.
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.
612 x 794 x 630 x 820 = 251030404800
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
794 : 1, 2, 397, 794
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,794,630,820, is 2.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
794:2x 397
630:2x 3x 3x 5x 7
820:2x 2x 5x 41
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 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 251030404800/(2x360)
LCM = 251030404800/720
LCM = 348653340
Thus, we can understand that the LCM of 612,794,630,820 is 348653340.
