Given numbers are 658,206,423,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,206,423,764 is 233007012.
Find LCM of 658,206,423,764 with Prime Factorization
| 2 | 658, 206, 423, 764 |
| 47 | 329, 103, 423, 382 |
| 7, 103, 9, 382 |
Multiply the prime numbers at the bottom and the left side.
2 x 47 x 7 x 103 x 9 x 382 = 233007012
Therefore, the lowest common multiple of 658,206,423,764 is 233007012.
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.
658 x 206 x 423 x 764 = 43805318256
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
206 : 1, 2, 103, 206
423 : 1, 3, 9, 47, 141, 423
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,206,423,764, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
206:2x 103
423:3x 3x 47
764:2x 2x 191
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 47 = 188
Therefore, the value for common factors is 188.
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 = 43805318256/(1x188)
LCM = 43805318256/188
LCM = 233007012
Thus, we can understand that the LCM of 658,206,423,764 is 233007012.
