Given numbers are 715,820,238,469,692
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,820,238,469,692 is 161740118540.
Find LCM of 715,820,238,469,692 with Prime Factorization
| 2 | 715, 820, 238, 469, 692 |
| 2 | 715, 410, 119, 469, 346 |
| 5 | 715, 205, 119, 469, 173 |
| 7 | 143, 41, 119, 469, 173 |
| 143, 41, 17, 67, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 143 x 41 x 17 x 67 x 173 = 161740118540
Therefore, the lowest common multiple of 715,820,238,469,692 is 161740118540.
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.
715 x 820 x 238 x 469 x 692 = 45287233191200
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
238 : 1, 2, 7, 14, 17, 34, 119, 238
469 : 1, 7, 67, 469
692 : 1, 2, 4, 173, 346, 692
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,820,238,469,692, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
820:2x 2x 5x 41
238:2x 7x 17
469:7x 67
692:2x 2x 173
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 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 45287233191200/(1x280)
LCM = 45287233191200/280
LCM = 161740118540
Thus, we can understand that the LCM of 715,820,238,469,692 is 161740118540.
