Given numbers are 430,975,340,115,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,975,340,115,257 is 16851669900.
Find LCM of 430,975,340,115,257 with Prime Factorization
2 | 430, 975, 340, 115, 257 |
5 | 215, 975, 170, 115, 257 |
43, 195, 34, 23, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 195 x 34 x 23 x 257 = 16851669900
Therefore, the lowest common multiple of 430,975,340,115,257 is 16851669900.
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.
430 x 975 x 340 x 115 x 257 = 4212917475000
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
115 : 1, 5, 23, 115
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,975,340,115,257, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
975:3x 5x 5x 13
340:2x 2x 5x 17
115:5x 23
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5 = 250
Therefore, the value for common factors is 250.
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 = 4212917475000/(1x250)
LCM = 4212917475000/250
LCM = 16851669900
Thus, we can understand that the LCM of 430,975,340,115,257 is 16851669900.
