Given numbers are 853,745,759,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,745,759,642 is 103219286610.
Find LCM of 853,745,759,642 with Prime Factorization
| 3 | 853, 745, 759, 642 |
| 853, 745, 253, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 853 x 745 x 253 x 214 = 103219286610
Therefore, the lowest common multiple of 853,745,759,642 is 103219286610.
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.
853 x 745 x 759 x 642 = 309657859830
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.
853 : 1, 853
745 : 1, 5, 149, 745
759 : 1, 3, 11, 23, 33, 69, 253, 759
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,745,759,642, is 1.
Now, the common factors can be found like this.
853:853
745:5x 149
759:3x 11x 23
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 309657859830/(1x3)
LCM = 309657859830/3
LCM = 103219286610
Thus, we can understand that the LCM of 853,745,759,642 is 103219286610.
