Given numbers are 922,630,138,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 922,630,138,315 is 6679890.
Find LCM of 922,630,138,315 with Prime Factorization
| 2 | 922, 630, 138, 315 |
| 3 | 461, 315, 69, 315 |
| 3 | 461, 105, 23, 105 |
| 5 | 461, 35, 23, 35 |
| 7 | 461, 7, 23, 7 |
| 461, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 461 x 1 x 23 x 1 = 6679890
Therefore, the lowest common multiple of 922,630,138,315 is 6679890.
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.
922 x 630 x 138 x 315 = 25249984200
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.
922 : 1, 2, 461, 922
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
138 : 1, 2, 3, 6, 23, 46, 69, 138
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 922,630,138,315, is 1.
Now, the common factors can be found like this.
922:2x 461
630:2x 3x 3x 5x 7
138:2x 3x 23
315:3x 3x 5x 7
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 5x 7 = 3780
Therefore, the value for common factors is 3780.
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 = 25249984200/(1x3780)
LCM = 25249984200/3780
LCM = 6679890
Thus, we can understand that the LCM of 922,630,138,315 is 6679890.
