Given numbers are 619,363,689,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,363,689,345 is 17803866795.
Find LCM of 619,363,689,345 with Prime Factorization
| 3 | 619, 363, 689, 345 |
| 619, 121, 689, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 619 x 121 x 689 x 115 = 17803866795
Therefore, the lowest common multiple of 619,363,689,345 is 17803866795.
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 363 x 689 x 345 = 53411600385
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
363 : 1, 3, 11, 33, 121, 363
689 : 1, 13, 53, 689
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,363,689,345, is 1.
Now, the common factors can be found like this.
619:619
363:3x 11x 11
689:13x 53
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 53411600385/(1x3)
LCM = 53411600385/3
LCM = 17803866795
Thus, we can understand that the LCM of 619,363,689,345 is 17803866795.
