Given numbers are 381,119,418,931,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,119,418,931,389 is 51605484546.
Find LCM of 381,119,418,931,389 with Prime Factorization
7 | 381, 119, 418, 931, 389 |
19 | 381, 17, 418, 133, 389 |
381, 17, 22, 7, 389 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 381 x 17 x 22 x 7 x 389 = 51605484546
Therefore, the lowest common multiple of 381,119,418,931,389 is 51605484546.
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.
381 x 119 x 418 x 931 x 389 = 6863529444618
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.
381 : 1, 3, 127, 381
119 : 1, 7, 17, 119
418 : 1, 2, 11, 19, 22, 38, 209, 418
931 : 1, 7, 19, 49, 133, 931
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,119,418,931,389, is 1.
Now, the common factors can be found like this.
381:3x 127
119:7x 17
418:2x 11x 19
931:7x 7x 19
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 6863529444618/(1x133)
LCM = 6863529444618/133
LCM = 51605484546
Thus, we can understand that the LCM of 381,119,418,931,389 is 51605484546.
