Given numbers are 178,849,579,294,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,849,579,294,780 is 185790898020.
Find LCM of 178,849,579,294,780 with Prime Factorization
| 2 | 178, 849, 579, 294, 780 |
| 3 | 89, 849, 579, 147, 390 |
| 89, 283, 193, 49, 130 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 283 x 193 x 49 x 130 = 185790898020
Therefore, the lowest common multiple of 178,849,579,294,780 is 185790898020.
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.
178 x 849 x 579 x 294 x 780 = 20065416986160
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.
178 : 1, 2, 89, 178
849 : 1, 3, 283, 849
579 : 1, 3, 193, 579
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
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 178,849,579,294,780, is 1.
Now, the common factors can be found like this.
178:2x 89
849:3x 283
579:3x 193
294:2x 3x 7x 7
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 3 = 108
Therefore, the value for common factors is 108.
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 = 20065416986160/(1x108)
LCM = 20065416986160/108
LCM = 185790898020
Thus, we can understand that the LCM of 178,849,579,294,780 is 185790898020.
