Given numbers are 457,138,917,995,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,138,917,995,284 is 8171015743380.
Find LCM of 457,138,917,995,284 with Prime Factorization
| 2 | 457, 138, 917, 995, 284 |
| 457, 69, 917, 995, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 457 x 69 x 917 x 995 x 142 = 8171015743380
Therefore, the lowest common multiple of 457,138,917,995,284 is 8171015743380.
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.
457 x 138 x 917 x 995 x 284 = 16342031486760
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.
457 : 1, 457
138 : 1, 2, 3, 6, 23, 46, 69, 138
917 : 1, 7, 131, 917
995 : 1, 5, 199, 995
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,138,917,995,284, is 1.
Now, the common factors can be found like this.
457:457
138:2x 3x 23
917:7x 131
995:5x 199
284:2x 2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 16342031486760/(1x2)
LCM = 16342031486760/2
LCM = 8171015743380
Thus, we can understand that the LCM of 457,138,917,995,284 is 8171015743380.
