Given numbers are 437,299,753,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,299,753,645 is 919725495.
Find LCM of 437,299,753,645 with Prime Factorization
| 3 | 437, 299, 753, 645 |
| 23 | 437, 299, 251, 215 |
| 19, 13, 251, 215 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 19 x 13 x 251 x 215 = 919725495
Therefore, the lowest common multiple of 437,299,753,645 is 919725495.
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.
437 x 299 x 753 x 645 = 63461059155
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.
437 : 1, 19, 23, 437
299 : 1, 13, 23, 299
753 : 1, 3, 251, 753
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,299,753,645, is 1.
Now, the common factors can be found like this.
437:19x 23
299:13x 23
753:3x 251
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23 = 69
Therefore, the value for common factors is 69.
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 = 63461059155/(1x69)
LCM = 63461059155/69
LCM = 919725495
Thus, we can understand that the LCM of 437,299,753,645 is 919725495.
