Given numbers are 551,855,787,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,855,787,493 is 331732305.
Find LCM of 551,855,787,493 with Prime Factorization
19 | 551, 855, 787, 493 |
29 | 29, 45, 787, 493 |
1, 45, 787, 17 |
Multiply the prime numbers at the bottom and the left side.
19 x 29 x 1 x 45 x 787 x 17 = 331732305
Therefore, the lowest common multiple of 551,855,787,493 is 331732305.
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.
551 x 855 x 787 x 493 = 182784500055
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.
551 : 1, 19, 29, 551
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
787 : 1, 787
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,855,787,493, is 1.
Now, the common factors can be found like this.
551:19x 29
855:3x 3x 5x 19
787:787
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 29 = 551
Therefore, the value for common factors is 551.
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 = 182784500055/(1x551)
LCM = 182784500055/551
LCM = 331732305
Thus, we can understand that the LCM of 551,855,787,493 is 331732305.
