Given numbers are 635,140,805,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,140,805,397 is 162349180.
Find LCM of 635,140,805,397 with Prime Factorization
5 | 635, 140, 805, 397 |
7 | 127, 28, 161, 397 |
127, 4, 23, 397 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 127 x 4 x 23 x 397 = 162349180
Therefore, the lowest common multiple of 635,140,805,397 is 162349180.
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.
635 x 140 x 805 x 397 = 28411106500
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.
635 : 1, 5, 127, 635
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
805 : 1, 5, 7, 23, 35, 115, 161, 805
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,140,805,397, is 1.
Now, the common factors can be found like this.
635:5x 127
140:2x 2x 5x 7
805:5x 7x 23
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.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 28411106500/(1x175)
LCM = 28411106500/175
LCM = 162349180
Thus, we can understand that the LCM of 635,140,805,397 is 162349180.
