Given numbers are 140,901,791,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,901,791,689 is 185299660.
Find LCM of 140,901,791,689 with Prime Factorization
| 7 | 140, 901, 791, 689 |
| 53 | 20, 901, 113, 689 |
| 20, 17, 113, 13 |
Multiply the prime numbers at the bottom and the left side.
7 x 53 x 20 x 17 x 113 x 13 = 185299660
Therefore, the lowest common multiple of 140,901,791,689 is 185299660.
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 901 x 791 x 689 = 68746173860
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
901 : 1, 17, 53, 901
791 : 1, 7, 113, 791
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,901,791,689, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
901:17x 53
791:7x 113
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 53 = 371
Therefore, the value for common factors is 371.
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 = 68746173860/(1x371)
LCM = 68746173860/371
LCM = 185299660
Thus, we can understand that the LCM of 140,901,791,689 is 185299660.
