Given numbers are 671,481,645,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,481,645,754 is 12074114910.
Find LCM of 671,481,645,754 with Prime Factorization
13 | 671, 481, 645, 754 |
671, 37, 645, 58 |
Multiply the prime numbers at the bottom and the left side.
13 x 671 x 37 x 645 x 58 = 12074114910
Therefore, the lowest common multiple of 671,481,645,754 is 12074114910.
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.
671 x 481 x 645 x 754 = 156963493830
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.
671 : 1, 11, 61, 671
481 : 1, 13, 37, 481
645 : 1, 3, 5, 15, 43, 129, 215, 645
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,481,645,754, is 1.
Now, the common factors can be found like this.
671:11x 61
481:13x 37
645:3x 5x 43
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 156963493830/(1x13)
LCM = 156963493830/13
LCM = 12074114910
Thus, we can understand that the LCM of 671,481,645,754 is 12074114910.
