Given numbers are 451,535,645,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,535,645,642 is 62251530.
Find LCM of 451,535,645,642 with Prime Factorization
| 3 | 451, 535, 645, 642 |
| 5 | 451, 535, 215, 214 |
| 107 | 451, 107, 43, 214 |
| 451, 1, 43, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 107 x 451 x 1 x 43 x 2 = 62251530
Therefore, the lowest common multiple of 451,535,645,642 is 62251530.
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.
451 x 535 x 645 x 642 = 99913705650
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.
451 : 1, 11, 41, 451
535 : 1, 5, 107, 535
645 : 1, 3, 5, 15, 43, 129, 215, 645
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,535,645,642, is 1.
Now, the common factors can be found like this.
451:11x 41
535:5x 107
645:3x 5x 43
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 107 = 1605
Therefore, the value for common factors is 1605.
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 = 99913705650/(1x1605)
LCM = 99913705650/1605
LCM = 62251530
Thus, we can understand that the LCM of 451,535,645,642 is 62251530.
