Given numbers are 380,931,436,299,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,931,436,299,994 is 43085953820.
Find LCM of 380,931,436,299,994 with Prime Factorization
| 2 | 380, 931, 436, 299, 994 |
| 2 | 190, 931, 218, 299, 497 |
| 7 | 95, 931, 109, 299, 497 |
| 19 | 95, 133, 109, 299, 71 |
| 5, 7, 109, 299, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 5 x 7 x 109 x 299 x 71 = 43085953820
Therefore, the lowest common multiple of 380,931,436,299,994 is 43085953820.
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.
380 x 931 x 436 x 299 x 994 = 45843454864480
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
931 : 1, 7, 19, 49, 133, 931
436 : 1, 2, 4, 109, 218, 436
299 : 1, 13, 23, 299
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,931,436,299,994, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
931:7x 7x 19
436:2x 2x 109
299:13x 23
994:2x 7x 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 2x 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 45843454864480/(1x1064)
LCM = 45843454864480/1064
LCM = 43085953820
Thus, we can understand that the LCM of 380,931,436,299,994 is 43085953820.
