Given numbers are 342,128,894,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,128,894,817 is 140236416.
Find LCM of 342,128,894,817 with Prime Factorization
| 2 | 342, 128, 894, 817 |
| 3 | 171, 64, 447, 817 |
| 19 | 57, 64, 149, 817 |
| 3, 64, 149, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 3 x 64 x 149 x 43 = 140236416
Therefore, the lowest common multiple of 342,128,894,817 is 140236416.
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.
342 x 128 x 894 x 817 = 31973902848
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
128 : 1, 2, 4, 8, 16, 32, 64, 128
894 : 1, 2, 3, 6, 149, 298, 447, 894
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,128,894,817, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
128:2x 2x 2x 2x 2x 2x 2
894:2x 3x 149
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 31973902848/(1x228)
LCM = 31973902848/228
LCM = 140236416
Thus, we can understand that the LCM of 342,128,894,817 is 140236416.
