Given numbers are 780,398,328,272,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,398,328,272,738 is 1298260080.
Find LCM of 780,398,328,272,738 with Prime Factorization
| 2 | 780, 398, 328, 272, 738 |
| 2 | 390, 199, 164, 136, 369 |
| 2 | 195, 199, 82, 68, 369 |
| 3 | 195, 199, 41, 34, 369 |
| 41 | 65, 199, 41, 34, 123 |
| 65, 199, 1, 34, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 65 x 199 x 1 x 34 x 3 = 1298260080
Therefore, the lowest common multiple of 780,398,328,272,738 is 1298260080.
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.
780 x 398 x 328 x 272 x 738 = 20439806699520
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.
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
398 : 1, 2, 199, 398
328 : 1, 2, 4, 8, 41, 82, 164, 328
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,398,328,272,738, is 2.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
398:2x 199
328:2x 2x 2x 41
272:2x 2x 2x 2x 17
738:2x 3x 3x 41
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 2x 2x 2x 2x 3x 41 = 7872
Therefore, the value for common factors is 7872.
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 = 20439806699520/(2x7872)
LCM = 20439806699520/15744
LCM = 1298260080
Thus, we can understand that the LCM of 780,398,328,272,738 is 1298260080.
