Given numbers are 340,316,787,316
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,316,787,316 is 21138820.
Find LCM of 340,316,787,316 with Prime Factorization
| 2 | 340, 316, 787, 316 |
| 2 | 170, 158, 787, 158 |
| 79 | 85, 79, 787, 79 |
| 85, 1, 787, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 85 x 1 x 787 x 1 = 21138820
Therefore, the lowest common multiple of 340,316,787,316 is 21138820.
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.
340 x 316 x 787 x 316 = 26719468480
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
316 : 1, 2, 4, 79, 158, 316
787 : 1, 787
316 : 1, 2, 4, 79, 158, 316
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,316,787,316, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
316:2x 2x 79
787:787
316:2x 2x 79
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 2x 2x 79 = 1264
Therefore, the value for common factors is 1264.
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 = 26719468480/(1x1264)
LCM = 26719468480/1264
LCM = 21138820
Thus, we can understand that the LCM of 340,316,787,316 is 21138820.
