Given numbers are 942,614,257,872,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,614,257,872,639 is 6902215176744.
Find LCM of 942,614,257,872,639 with Prime Factorization
| 2 | 942, 614, 257, 872, 639 |
| 3 | 471, 307, 257, 436, 639 |
| 157, 307, 257, 436, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 307 x 257 x 436 x 213 = 6902215176744
Therefore, the lowest common multiple of 942,614,257,872,639 is 6902215176744.
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.
942 x 614 x 257 x 872 x 639 = 82826582120928
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
614 : 1, 2, 307, 614
257 : 1, 257
872 : 1, 2, 4, 8, 109, 218, 436, 872
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,614,257,872,639, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
614:2x 307
257:257
872:2x 2x 2x 109
639:3x 3x 71
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 = 82826582120928/(1x12)
LCM = 82826582120928/12
LCM = 6902215176744
Thus, we can understand that the LCM of 942,614,257,872,639 is 6902215176744.
