Given numbers are 363,689,780,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,689,780,780 is 5002140.
Find LCM of 363,689,780,780 with Prime Factorization
| 2 | 363, 689, 780, 780 |
| 2 | 363, 689, 390, 390 |
| 3 | 363, 689, 195, 195 |
| 5 | 121, 689, 65, 65 |
| 13 | 121, 689, 13, 13 |
| 121, 53, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 121 x 53 x 1 x 1 = 5002140
Therefore, the lowest common multiple of 363,689,780,780 is 5002140.
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.
363 x 689 x 780 x 780 = 152165098800
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.
363 : 1, 3, 11, 33, 121, 363
689 : 1, 13, 53, 689
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,689,780,780, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
689:13x 53
780:2x 2x 3x 5x 13
780:2x 2x 3x 5x 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 2x 3x 3x 5x 13x 13 = 30420
Therefore, the value for common factors is 30420.
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 = 152165098800/(1x30420)
LCM = 152165098800/30420
LCM = 5002140
Thus, we can understand that the LCM of 363,689,780,780 is 5002140.
