Given numbers are 438,152,774,755,846
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,152,774,755,846 is 152377983720.
Find LCM of 438,152,774,755,846 with Prime Factorization
| 2 | 438, 152, 774, 755, 846 |
| 3 | 219, 76, 387, 755, 423 |
| 3 | 73, 76, 129, 755, 141 |
| 73, 76, 43, 755, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 73 x 76 x 43 x 755 x 47 = 152377983720
Therefore, the lowest common multiple of 438,152,774,755,846 is 152377983720.
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.
438 x 152 x 774 x 755 x 846 = 32913644483520
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
152 : 1, 2, 4, 8, 19, 38, 76, 152
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
755 : 1, 5, 151, 755
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,152,774,755,846, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
152:2x 2x 2x 19
774:2x 3x 3x 43
755:5x 151
846:2x 3x 3x 47
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 3 = 216
Therefore, the value for common factors is 216.
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 = 32913644483520/(1x216)
LCM = 32913644483520/216
LCM = 152377983720
Thus, we can understand that the LCM of 438,152,774,755,846 is 152377983720.
