Given numbers are 411,681,640,646,314
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 411,681,640,646,314 is 3027957866880.
Find LCM of 411,681,640,646,314 with Prime Factorization
| 2 | 411, 681, 640, 646, 314 |
| 3 | 411, 681, 320, 323, 157 |
| 137, 227, 320, 323, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 227 x 320 x 323 x 157 = 3027957866880
Therefore, the lowest common multiple of 411,681,640,646,314 is 3027957866880.
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.
411 x 681 x 640 x 646 x 314 = 36335494402560
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.
411 : 1, 3, 137, 411
681 : 1, 3, 227, 681
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
646 : 1, 2, 17, 19, 34, 38, 323, 646
314 : 1, 2, 157, 314
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,681,640,646,314, is 1.
Now, the common factors can be found like this.
411:3x 137
681:3x 227
640:2x 2x 2x 2x 2x 2x 2x 5
646:2x 17x 19
314:2x 157
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 3 = 12
Therefore, the value for common factors is 12.
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 = 36335494402560/(1x12)
LCM = 36335494402560/12
LCM = 3027957866880
Thus, we can understand that the LCM of 411,681,640,646,314 is 3027957866880.
