Given numbers are 342,153,321,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,153,321,901 is 32971194.
Find LCM of 342,153,321,901 with Prime Factorization
| 3 | 342, 153, 321, 901 |
| 3 | 114, 51, 107, 901 |
| 17 | 38, 17, 107, 901 |
| 38, 1, 107, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 38 x 1 x 107 x 53 = 32971194
Therefore, the lowest common multiple of 342,153,321,901 is 32971194.
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.
342 x 153 x 321 x 901 = 15133778046
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
153 : 1, 3, 9, 17, 51, 153
321 : 1, 3, 107, 321
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,153,321,901, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
153:3x 3x 17
321:3x 107
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 15133778046/(1x459)
LCM = 15133778046/459
LCM = 32971194
Thus, we can understand that the LCM of 342,153,321,901 is 32971194.
