Given numbers are 741,754,436,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,754,436,688 is 1611503088.
Find LCM of 741,754,436,688 with Prime Factorization
| 2 | 741, 754, 436, 688 |
| 2 | 741, 377, 218, 344 |
| 13 | 741, 377, 109, 172 |
| 57, 29, 109, 172 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 57 x 29 x 109 x 172 = 1611503088
Therefore, the lowest common multiple of 741,754,436,688 is 1611503088.
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 754 x 436 x 688 = 167596321152
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
754 : 1, 2, 13, 26, 29, 58, 377, 754
436 : 1, 2, 4, 109, 218, 436
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,754,436,688, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
754:2x 13x 29
436:2x 2x 109
688:2x 2x 2x 2x 43
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 13 = 104
Therefore, the value for common factors is 104.
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 = 167596321152/(1x104)
LCM = 167596321152/104
LCM = 1611503088
Thus, we can understand that the LCM of 741,754,436,688 is 1611503088.
