Given numbers are 764,324,328,581,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,324,328,581,161 is 67810383144.
Find LCM of 764,324,328,581,161 with Prime Factorization
2 | 764, 324, 328, 581, 161 |
2 | 382, 162, 164, 581, 161 |
7 | 191, 81, 82, 581, 161 |
191, 81, 82, 83, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 191 x 81 x 82 x 83 x 23 = 67810383144
Therefore, the lowest common multiple of 764,324,328,581,161 is 67810383144.
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.
764 x 324 x 328 x 581 x 161 = 7594762912128
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.
764 : 1, 2, 4, 191, 382, 764
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
328 : 1, 2, 4, 8, 41, 82, 164, 328
581 : 1, 7, 83, 581
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,324,328,581,161, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
324:2x 2x 3x 3x 3x 3
328:2x 2x 2x 41
581:7x 83
161:7x 23
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 7 = 112
Therefore, the value for common factors is 112.
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 = 7594762912128/(1x112)
LCM = 7594762912128/112
LCM = 67810383144
Thus, we can understand that the LCM of 764,324,328,581,161 is 67810383144.
