Given numbers are 995,690,345,699,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,690,345,699,821 is 26266441830.
Find LCM of 995,690,345,699,821 with Prime Factorization
| 3 | 995, 690, 345, 699, 821 |
| 5 | 995, 230, 115, 233, 821 |
| 23 | 199, 46, 23, 233, 821 |
| 199, 2, 1, 233, 821 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 199 x 2 x 1 x 233 x 821 = 26266441830
Therefore, the lowest common multiple of 995,690,345,699,821 is 26266441830.
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 690 x 345 x 699 x 821 = 135928836470250
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
345 : 1, 3, 5, 15, 23, 69, 115, 345
699 : 1, 3, 233, 699
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,690,345,699,821, is 1.
Now, the common factors can be found like this.
995:5x 199
690:2x 3x 5x 23
345:3x 5x 23
699:3x 233
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 23 = 5175
Therefore, the value for common factors is 5175.
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 = 135928836470250/(1x5175)
LCM = 135928836470250/5175
LCM = 26266441830
Thus, we can understand that the LCM of 995,690,345,699,821 is 26266441830.
