Given numbers are 756,894,980,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,894,980,356 is 350886060.
Find LCM of 756,894,980,356 with Prime Factorization
| 2 | 756, 894, 980, 356 |
| 2 | 378, 447, 490, 178 |
| 3 | 189, 447, 245, 89 |
| 7 | 63, 149, 245, 89 |
| 9, 149, 35, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 9 x 149 x 35 x 89 = 350886060
Therefore, the lowest common multiple of 756,894,980,356 is 350886060.
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.
756 x 894 x 980 x 356 = 235795432320
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
894 : 1, 2, 3, 6, 149, 298, 447, 894
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
356 : 1, 2, 4, 89, 178, 356
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,894,980,356, is 2.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
894:2x 3x 149
980:2x 2x 5x 7x 7
356:2x 2x 89
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 235795432320/(2x336)
LCM = 235795432320/672
LCM = 350886060
Thus, we can understand that the LCM of 756,894,980,356 is 350886060.
