Given numbers are 450,248,418,691,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,248,418,691,397 is 3199256339400.
Find LCM of 450,248,418,691,397 with Prime Factorization
2 | 450, 248, 418, 691, 397 |
225, 124, 209, 691, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 225 x 124 x 209 x 691 x 397 = 3199256339400
Therefore, the lowest common multiple of 450,248,418,691,397 is 3199256339400.
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.
450 x 248 x 418 x 691 x 397 = 12797025357600
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
248 : 1, 2, 4, 8, 31, 62, 124, 248
418 : 1, 2, 11, 19, 22, 38, 209, 418
691 : 1, 691
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,248,418,691,397, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
248:2x 2x 2x 31
418:2x 11x 19
691:691
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 12797025357600/(1x4)
LCM = 12797025357600/4
LCM = 3199256339400
Thus, we can understand that the LCM of 450,248,418,691,397 is 3199256339400.
