Given numbers are 442,450,790,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,450,790,553 is 54995850.
Find LCM of 442,450,790,553 with Prime Factorization
| 2 | 442, 450, 790, 553 |
| 5 | 221, 225, 395, 553 |
| 79 | 221, 45, 79, 553 |
| 221, 45, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 221 x 45 x 1 x 7 = 54995850
Therefore, the lowest common multiple of 442,450,790,553 is 54995850.
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.
442 x 450 x 790 x 553 = 86893443000
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
790 : 1, 2, 5, 10, 79, 158, 395, 790
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,450,790,553, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
450:2x 3x 3x 5x 5
790:2x 5x 79
553:7x 79
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 5x 79 = 1580
Therefore, the value for common factors is 1580.
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 = 86893443000/(1x1580)
LCM = 86893443000/1580
LCM = 54995850
Thus, we can understand that the LCM of 442,450,790,553 is 54995850.
