Given numbers are 764,905,713,705,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 764,905,713,705,342 is 3962100031020.
Find LCM of 764,905,713,705,342 with Prime Factorization
| 2 | 764, 905, 713, 705, 342 |
| 3 | 382, 905, 713, 705, 171 |
| 5 | 382, 905, 713, 235, 57 |
| 382, 181, 713, 47, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 382 x 181 x 713 x 47 x 57 = 3962100031020
Therefore, the lowest common multiple of 764,905,713,705,342 is 3962100031020.
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 905 x 713 x 705 x 342 = 118863000930600
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
905 : 1, 5, 181, 905
713 : 1, 23, 31, 713
705 : 1, 3, 5, 15, 47, 141, 235, 705
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,905,713,705,342, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
905:5x 181
713:23x 31
705:3x 5x 47
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 118863000930600/(1x30)
LCM = 118863000930600/30
LCM = 3962100031020
Thus, we can understand that the LCM of 764,905,713,705,342 is 3962100031020.
