Given numbers are 413,646,639,692
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 413,646,639,692 is 58987437012.
Find LCM of 413,646,639,692 with Prime Factorization
| 2 | 413, 646, 639, 692 |
| 413, 323, 639, 346 |
Multiply the prime numbers at the bottom and the left side.
2 x 413 x 323 x 639 x 346 = 58987437012
Therefore, the lowest common multiple of 413,646,639,692 is 58987437012.
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.
413 x 646 x 639 x 692 = 117974874024
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.
413 : 1, 7, 59, 413
646 : 1, 2, 17, 19, 34, 38, 323, 646
639 : 1, 3, 9, 71, 213, 639
692 : 1, 2, 4, 173, 346, 692
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,646,639,692, is 1.
Now, the common factors can be found like this.
413:7x 59
646:2x 17x 19
639:3x 3x 71
692:2x 2x 173
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 = 117974874024/(1x2)
LCM = 117974874024/2
LCM = 58987437012
Thus, we can understand that the LCM of 413,646,639,692 is 58987437012.
