Given numbers are 817,403,312,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,403,312,650 is 197550600.
Find LCM of 817,403,312,650 with Prime Factorization
| 2 | 817, 403, 312, 650 |
| 13 | 817, 403, 156, 325 |
| 817, 31, 12, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 817 x 31 x 12 x 25 = 197550600
Therefore, the lowest common multiple of 817,403,312,650 is 197550600.
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 403 x 312 x 650 = 66772102800
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
403 : 1, 13, 31, 403
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,403,312,650, is 1.
Now, the common factors can be found like this.
817:19x 43
403:13x 31
312:2x 2x 2x 3x 13
650:2x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 66772102800/(1x338)
LCM = 66772102800/338
LCM = 197550600
Thus, we can understand that the LCM of 817,403,312,650 is 197550600.
