Given numbers are 790,186,156,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,186,156,961 is 59216820.
Find LCM of 790,186,156,961 with Prime Factorization
| 2 | 790, 186, 156, 961 |
| 3 | 395, 93, 78, 961 |
| 31 | 395, 31, 26, 961 |
| 395, 1, 26, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 395 x 1 x 26 x 31 = 59216820
Therefore, the lowest common multiple of 790,186,156,961 is 59216820.
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.
790 x 186 x 156 x 961 = 22028657040
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
186 : 1, 2, 3, 6, 31, 62, 93, 186
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,186,156,961, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
186:2x 3x 31
156:2x 2x 3x 13
961:31x 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 2x 3x 31 = 372
Therefore, the value for common factors is 372.
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 = 22028657040/(1x372)
LCM = 22028657040/372
LCM = 59216820
Thus, we can understand that the LCM of 790,186,156,961 is 59216820.
