Given numbers are 722,968,221,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,968,221,890 is 34366463560.
Find LCM of 722,968,221,890 with Prime Factorization
2 | 722, 968, 221, 890 |
361, 484, 221, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 361 x 484 x 221 x 445 = 34366463560
Therefore, the lowest common multiple of 722,968,221,890 is 34366463560.
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 968 x 221 x 890 = 137465854240
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
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
221 : 1, 13, 17, 221
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,968,221,890, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
968:2x 2x 2x 11x 11
221:13x 17
890:2x 5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 137465854240/(1x4)
LCM = 137465854240/4
LCM = 34366463560
Thus, we can understand that the LCM of 722,968,221,890 is 34366463560.
