Given numbers are 403,713,603,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,713,603,868 is 156497796.
Find LCM of 403,713,603,868 with Prime Factorization
| 31 | 403, 713, 603, 868 |
| 13, 23, 603, 28 |
Multiply the prime numbers at the bottom and the left side.
31 x 13 x 23 x 603 x 28 = 156497796
Therefore, the lowest common multiple of 403,713,603,868 is 156497796.
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.
403 x 713 x 603 x 868 = 150394381956
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.
403 : 1, 13, 31, 403
713 : 1, 23, 31, 713
603 : 1, 3, 9, 67, 201, 603
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,713,603,868, is 1.
Now, the common factors can be found like this.
403:13x 31
713:23x 31
603:3x 3x 67
868:2x 2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31x 31 = 961
Therefore, the value for common factors is 961.
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 = 150394381956/(1x961)
LCM = 150394381956/961
LCM = 156497796
Thus, we can understand that the LCM of 403,713,603,868 is 156497796.
