Given numbers are 617,910,406,516
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 617,910,406,516 is 4200918540.
Find LCM of 617,910,406,516 with Prime Factorization
| 2 | 617, 910, 406, 516 |
| 7 | 617, 455, 203, 258 |
| 617, 65, 29, 258 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 617 x 65 x 29 x 258 = 4200918540
Therefore, the lowest common multiple of 617,910,406,516 is 4200918540.
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.
617 x 910 x 406 x 516 = 117625719120
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.
617 : 1, 617
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
406 : 1, 2, 7, 14, 29, 58, 203, 406
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,910,406,516, is 1.
Now, the common factors can be found like this.
617:617
910:2x 5x 7x 13
406:2x 7x 29
516:2x 2x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 117625719120/(1x28)
LCM = 117625719120/28
LCM = 4200918540
Thus, we can understand that the LCM of 617,910,406,516 is 4200918540.
