Given numbers are 649,281,843,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,281,843,742 is 405953394.
Find LCM of 649,281,843,742 with Prime Factorization
281 | 649, 281, 843, 742 |
649, 1, 3, 742 |
Multiply the prime numbers at the bottom and the left side.
281 x 649 x 1 x 3 x 742 = 405953394
Therefore, the lowest common multiple of 649,281,843,742 is 405953394.
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.
649 x 281 x 843 x 742 = 114072903714
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.
649 : 1, 11, 59, 649
281 : 1, 281
843 : 1, 3, 281, 843
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,281,843,742, is 1.
Now, the common factors can be found like this.
649:11x 59
281:281
843:3x 281
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
281 = 281
Therefore, the value for common factors is 281.
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 = 114072903714/(1x281)
LCM = 114072903714/281
LCM = 405953394
Thus, we can understand that the LCM of 649,281,843,742 is 405953394.
