Given numbers are 167,506,391,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 167,506,391,990 is 64644030.
Find LCM of 167,506,391,990 with Prime Factorization
| 2 | 167, 506, 391, 990 |
| 11 | 167, 253, 391, 495 |
| 23 | 167, 23, 391, 45 |
| 167, 1, 17, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 167 x 1 x 17 x 45 = 64644030
Therefore, the lowest common multiple of 167,506,391,990 is 64644030.
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.
167 x 506 x 391 x 990 = 32709879180
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.
167 : 1, 167
506 : 1, 2, 11, 22, 23, 46, 253, 506
391 : 1, 17, 23, 391
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 167,506,391,990, is 1.
Now, the common factors can be found like this.
167:167
506:2x 11x 23
391:17x 23
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 23 = 506
Therefore, the value for common factors is 506.
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 = 32709879180/(1x506)
LCM = 32709879180/506
LCM = 64644030
Thus, we can understand that the LCM of 167,506,391,990 is 64644030.
