Given numbers are 724,905,901,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,905,901,217 is 707771540.
Find LCM of 724,905,901,217 with Prime Factorization
181 | 724, 905, 901, 217 |
4, 5, 901, 217 |
Multiply the prime numbers at the bottom and the left side.
181 x 4 x 5 x 901 x 217 = 707771540
Therefore, the lowest common multiple of 724,905,901,217 is 707771540.
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 905 x 901 x 217 = 128106648740
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
905 : 1, 5, 181, 905
901 : 1, 17, 53, 901
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,905,901,217, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
905:5x 181
901:17x 53
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
181 = 181
Therefore, the value for common factors is 181.
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 = 128106648740/(1x181)
LCM = 128106648740/181
LCM = 707771540
Thus, we can understand that the LCM of 724,905,901,217 is 707771540.
