Given numbers are 346,630,196,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 346,630,196,920 is 70189560.
Find LCM of 346,630,196,920 with Prime Factorization
2 | 346, 630, 196, 920 |
2 | 173, 315, 98, 460 |
5 | 173, 315, 49, 230 |
7 | 173, 63, 49, 46 |
173, 9, 7, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 173 x 9 x 7 x 46 = 70189560
Therefore, the lowest common multiple of 346,630,196,920 is 70189560.
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.
346 x 630 x 196 x 920 = 39306153600
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.
346 : 1, 2, 173, 346
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
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 346,630,196,920, is 2.
Now, the common factors can be found like this.
346:2x 173
630:2x 3x 3x 5x 7
196:2x 2x 7x 7
920:2x 2x 2x 5x 23
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 39306153600/(2x280)
LCM = 39306153600/560
LCM = 70189560
Thus, we can understand that the LCM of 346,630,196,920 is 70189560.
