Given numbers are 619,103,442,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,103,442,728 is 789056632.
Find LCM of 619,103,442,728 with Prime Factorization
2 | 619, 103, 442, 728 |
13 | 619, 103, 221, 364 |
619, 103, 17, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 619 x 103 x 17 x 28 = 789056632
Therefore, the lowest common multiple of 619,103,442,728 is 789056632.
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.
619 x 103 x 442 x 728 = 20515472432
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.
619 : 1, 619
103 : 1, 103
442 : 1, 2, 13, 17, 26, 34, 221, 442
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,103,442,728, is 1.
Now, the common factors can be found like this.
619:619
103:103
442:2x 13x 17
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 20515472432/(1x26)
LCM = 20515472432/26
LCM = 789056632
Thus, we can understand that the LCM of 619,103,442,728 is 789056632.
