Given numbers are 732,421,361,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 732,421,361,423 is 15686262972.
Find LCM of 732,421,361,423 with Prime Factorization
| 3 | 732, 421, 361, 423 |
| 244, 421, 361, 141 |
Multiply the prime numbers at the bottom and the left side.
3 x 244 x 421 x 361 x 141 = 15686262972
Therefore, the lowest common multiple of 732,421,361,423 is 15686262972.
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.
732 x 421 x 361 x 423 = 47058788916
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.
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
421 : 1, 421
361 : 1, 19, 361
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,421,361,423, is 1.
Now, the common factors can be found like this.
732:2x 2x 3x 61
421:421
361:19x 19
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 47058788916/(1x3)
LCM = 47058788916/3
LCM = 15686262972
Thus, we can understand that the LCM of 732,421,361,423 is 15686262972.
