Given numbers are 722,669,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,669,388 is 93705492.
Find LCM of 722,669,388 with Prime Factorization
| 2 | 722, 669, 388 |
| 361, 669, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 361 x 669 x 194 = 93705492
Therefore, the lowest common multiple of 722,669,388 is 93705492.
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.
722 x 669 x 388 = 187410984
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.
722 : 1, 2, 19, 38, 361, 722
669 : 1, 3, 223, 669
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,669,388, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
669:3x 223
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 187410984/(1x2)
LCM = 187410984/2
LCM = 93705492
Thus, we can understand that the LCM of 722,669,388 is 93705492.
