Given numbers are 140,289,901,545,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,289,901,545,838 is 97935978980.
Find LCM of 140,289,901,545,838 with Prime Factorization
2 | 140, 289, 901, 545, 838 |
5 | 70, 289, 901, 545, 419 |
17 | 14, 289, 901, 109, 419 |
14, 17, 53, 109, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 14 x 17 x 53 x 109 x 419 = 97935978980
Therefore, the lowest common multiple of 140,289,901,545,838 is 97935978980.
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.
140 x 289 x 901 x 545 x 838 = 16649116426600
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
289 : 1, 17, 289
901 : 1, 17, 53, 901
545 : 1, 5, 109, 545
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,289,901,545,838, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
289:17x 17
901:17x 53
545:5x 109
838:2x 419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 16649116426600/(1x170)
LCM = 16649116426600/170
LCM = 97935978980
Thus, we can understand that the LCM of 140,289,901,545,838 is 97935978980.
