Given numbers are 397,781,185,360,982
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,781,185,360,982 is 2027809986840.
Find LCM of 397,781,185,360,982 with Prime Factorization
| 2 | 397, 781, 185, 360, 982 |
| 5 | 397, 781, 185, 180, 491 |
| 397, 781, 37, 36, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 397 x 781 x 37 x 36 x 491 = 2027809986840
Therefore, the lowest common multiple of 397,781,185,360,982 is 2027809986840.
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.
397 x 781 x 185 x 360 x 982 = 20278099868400
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.
397 : 1, 397
781 : 1, 11, 71, 781
185 : 1, 5, 37, 185
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
982 : 1, 2, 491, 982
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,781,185,360,982, is 1.
Now, the common factors can be found like this.
397:397
781:11x 71
185:5x 37
360:2x 2x 2x 3x 3x 5
982:2x 491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 20278099868400/(1x10)
LCM = 20278099868400/10
LCM = 2027809986840
Thus, we can understand that the LCM of 397,781,185,360,982 is 2027809986840.
