Given numbers are 669,615,378,369,181
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,615,378,369,181 is 3127728870.
Find LCM of 669,615,378,369,181 with Prime Factorization
| 3 | 669, 615, 378, 369, 181 |
| 3 | 223, 205, 126, 123, 181 |
| 41 | 223, 205, 42, 41, 181 |
| 223, 5, 42, 1, 181 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 41 x 223 x 5 x 42 x 1 x 181 = 3127728870
Therefore, the lowest common multiple of 669,615,378,369,181 is 3127728870.
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.
669 x 615 x 378 x 369 x 181 = 10387187577270
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.
669 : 1, 3, 223, 669
615 : 1, 3, 5, 15, 41, 123, 205, 615
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
369 : 1, 3, 9, 41, 123, 369
181 : 1, 181
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,615,378,369,181, is 1.
Now, the common factors can be found like this.
669:3x 223
615:3x 5x 41
378:2x 3x 3x 3x 7
369:3x 3x 41
181:181
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 3x 3x 41 = 3321
Therefore, the value for common factors is 3321.
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 = 10387187577270/(1x3321)
LCM = 10387187577270/3321
LCM = 3127728870
Thus, we can understand that the LCM of 669,615,378,369,181 is 3127728870.
