Given numbers are 817,817,357,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,817,357,988 is 15166788.
Find LCM of 817,817,357,988 with Prime Factorization
| 19 | 817, 817, 357, 988 |
| 43 | 43, 43, 357, 52 |
| 1, 1, 357, 52 |
Multiply the prime numbers at the bottom and the left side.
19 x 43 x 1 x 1 x 357 x 52 = 15166788
Therefore, the lowest common multiple of 817,817,357,988 is 15166788.
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.
817 x 817 x 357 x 988 = 235434050124
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.
817 : 1, 19, 43, 817
817 : 1, 19, 43, 817
357 : 1, 3, 7, 17, 21, 51, 119, 357
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,817,357,988, is 1.
Now, the common factors can be found like this.
817:19x 43
817:19x 43
357:3x 7x 17
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19x 43 = 15523
Therefore, the value for common factors is 15523.
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 = 235434050124/(1x15523)
LCM = 235434050124/15523
LCM = 15166788
Thus, we can understand that the LCM of 817,817,357,988 is 15166788.
