Given numbers are 724,156,397,224,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,156,397,224,488 is 38292307872.
Find LCM of 724,156,397,224,488 with Prime Factorization
| 2 | 724, 156, 397, 224, 488 |
| 2 | 362, 78, 397, 112, 244 |
| 2 | 181, 39, 397, 56, 122 |
| 181, 39, 397, 28, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 181 x 39 x 397 x 28 x 61 = 38292307872
Therefore, the lowest common multiple of 724,156,397,224,488 is 38292307872.
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.
724 x 156 x 397 x 224 x 488 = 4901415407616
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.
724 : 1, 2, 4, 181, 362, 724
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
397 : 1, 397
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,156,397,224,488, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
156:2x 2x 3x 13
397:397
224:2x 2x 2x 2x 2x 7
488:2x 2x 2x 61
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 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 4901415407616/(1x128)
LCM = 4901415407616/128
LCM = 38292307872
Thus, we can understand that the LCM of 724,156,397,224,488 is 38292307872.
