Given numbers are 491,125,138,118,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,125,138,118,387 is 64463267250.
Find LCM of 491,125,138,118,387 with Prime Factorization
| 2 | 491, 125, 138, 118, 387 |
| 3 | 491, 125, 69, 59, 387 |
| 491, 125, 23, 59, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 491 x 125 x 23 x 59 x 129 = 64463267250
Therefore, the lowest common multiple of 491,125,138,118,387 is 64463267250.
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.
491 x 125 x 138 x 118 x 387 = 386779603500
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.
491 : 1, 491
125 : 1, 5, 25, 125
138 : 1, 2, 3, 6, 23, 46, 69, 138
118 : 1, 2, 59, 118
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,125,138,118,387, is 1.
Now, the common factors can be found like this.
491:491
125:5x 5x 5
138:2x 3x 23
118:2x 59
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 386779603500/(1x6)
LCM = 386779603500/6
LCM = 64463267250
Thus, we can understand that the LCM of 491,125,138,118,387 is 64463267250.
