Given numbers are 154,678,670,350
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,678,670,350 is 87445050.
Find LCM of 154,678,670,350 with Prime Factorization
| 2 | 154, 678, 670, 350 |
| 5 | 77, 339, 335, 175 |
| 7 | 77, 339, 67, 35 |
| 11, 339, 67, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 339 x 67 x 5 = 87445050
Therefore, the lowest common multiple of 154,678,670,350 is 87445050.
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.
154 x 678 x 670 x 350 = 24484614000
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
678 : 1, 2, 3, 6, 113, 226, 339, 678
670 : 1, 2, 5, 10, 67, 134, 335, 670
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,678,670,350, is 2.
Now, the common factors can be found like this.
154:2x 7x 11
678:2x 3x 113
670:2x 5x 67
350:2x 5x 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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 24484614000/(2x140)
LCM = 24484614000/280
LCM = 87445050
Thus, we can understand that the LCM of 154,678,670,350 is 87445050.
