Given numbers are 859,237,642,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,237,642,434 is 9453987354.
Find LCM of 859,237,642,434 with Prime Factorization
| 2 | 859, 237, 642, 434 |
| 3 | 859, 237, 321, 217 |
| 859, 79, 107, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 859 x 79 x 107 x 217 = 9453987354
Therefore, the lowest common multiple of 859,237,642,434 is 9453987354.
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.
859 x 237 x 642 x 434 = 56723924124
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.
859 : 1, 859
237 : 1, 3, 79, 237
642 : 1, 2, 3, 6, 107, 214, 321, 642
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,237,642,434, is 1.
Now, the common factors can be found like this.
859:859
237:3x 79
642:2x 3x 107
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 56723924124/(1x6)
LCM = 56723924124/6
LCM = 9453987354
Thus, we can understand that the LCM of 859,237,642,434 is 9453987354.
