Given numbers are 741,646,418,590
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,646,418,590 is 81754530.
Find LCM of 741,646,418,590 with Prime Factorization
| 2 | 741, 646, 418, 590 |
| 19 | 741, 323, 209, 295 |
| 39, 17, 11, 295 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 39 x 17 x 11 x 295 = 81754530
Therefore, the lowest common multiple of 741,646,418,590 is 81754530.
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.
741 x 646 x 418 x 590 = 118053541320
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
646 : 1, 2, 17, 19, 34, 38, 323, 646
418 : 1, 2, 11, 19, 22, 38, 209, 418
590 : 1, 2, 5, 10, 59, 118, 295, 590
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,646,418,590, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
646:2x 17x 19
418:2x 11x 19
590:2x 5x 59
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 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 118053541320/(1x1444)
LCM = 118053541320/1444
LCM = 81754530
Thus, we can understand that the LCM of 741,646,418,590 is 81754530.
