Given numbers are 298,393,691,917,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,393,691,917,910 is 36821227170.
Find LCM of 298,393,691,917,910 with Prime Factorization
| 2 | 298, 393, 691, 917, 910 |
| 7 | 149, 393, 691, 917, 455 |
| 131 | 149, 393, 691, 131, 65 |
| 149, 3, 691, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 131 x 149 x 3 x 691 x 1 x 65 = 36821227170
Therefore, the lowest common multiple of 298,393,691,917,910 is 36821227170.
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.
298 x 393 x 691 x 917 x 910 = 67530130629780
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.
298 : 1, 2, 149, 298
393 : 1, 3, 131, 393
691 : 1, 691
917 : 1, 7, 131, 917
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,393,691,917,910, is 1.
Now, the common factors can be found like this.
298:2x 149
393:3x 131
691:691
917:7x 131
910:2x 5x 7x 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 7x 131 = 1834
Therefore, the value for common factors is 1834.
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 = 67530130629780/(1x1834)
LCM = 67530130629780/1834
LCM = 36821227170
Thus, we can understand that the LCM of 298,393,691,917,910 is 36821227170.
