Given numbers are 432,284,308,358,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 432,284,308,358,721 is 43543474128.
Find LCM of 432,284,308,358,721 with Prime Factorization
| 2 | 432, 284, 308, 358, 721 |
| 2 | 216, 142, 154, 179, 721 |
| 7 | 108, 71, 77, 179, 721 |
| 108, 71, 11, 179, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 108 x 71 x 11 x 179 x 103 = 43543474128
Therefore, the lowest common multiple of 432,284,308,358,721 is 43543474128.
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.
432 x 284 x 308 x 358 x 721 = 9753738204672
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
284 : 1, 2, 4, 71, 142, 284
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
358 : 1, 2, 179, 358
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,284,308,358,721, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
284:2x 2x 71
308:2x 2x 7x 11
358:2x 179
721:7x 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 2x 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 9753738204672/(1x224)
LCM = 9753738204672/224
LCM = 43543474128
Thus, we can understand that the LCM of 432,284,308,358,721 is 43543474128.
