Given numbers are 995,493,990,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,493,990,380 is 3690785340.
Find LCM of 995,493,990,380 with Prime Factorization
| 2 | 995, 493, 990, 380 |
| 5 | 995, 493, 495, 190 |
| 199, 493, 99, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 199 x 493 x 99 x 38 = 3690785340
Therefore, the lowest common multiple of 995,493,990,380 is 3690785340.
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 493 x 990 x 380 = 184539267000
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
493 : 1, 17, 29, 493
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,493,990,380, is 1.
Now, the common factors can be found like this.
995:5x 199
493:17x 29
990:2x 3x 3x 5x 11
380:2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 184539267000/(1x50)
LCM = 184539267000/50
LCM = 3690785340
Thus, we can understand that the LCM of 995,493,990,380 is 3690785340.
