Given numbers are 995,722,398,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,722,398,309 is 221982510.
Find LCM of 995,722,398,309 with Prime Factorization
2 | 995, 722, 398, 309 |
199 | 995, 361, 199, 309 |
5, 361, 1, 309 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 5 x 361 x 1 x 309 = 221982510
Therefore, the lowest common multiple of 995,722,398,309 is 221982510.
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.
995 x 722 x 398 x 309 = 88349038980
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.
995 : 1, 5, 199, 995
722 : 1, 2, 19, 38, 361, 722
398 : 1, 2, 199, 398
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,722,398,309, is 1.
Now, the common factors can be found like this.
995:5x 199
722:2x 19x 19
398:2x 199
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 199 = 398
Therefore, the value for common factors is 398.
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 = 88349038980/(1x398)
LCM = 88349038980/398
LCM = 221982510
Thus, we can understand that the LCM of 995,722,398,309 is 221982510.
