Given numbers are 756,580,308,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,580,308,889 is 153139140.
Find LCM of 756,580,308,889 with Prime Factorization
| 2 | 756, 580, 308, 889 |
| 2 | 378, 290, 154, 889 |
| 7 | 189, 145, 77, 889 |
| 27, 145, 11, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 27 x 145 x 11 x 127 = 153139140
Therefore, the lowest common multiple of 756,580,308,889 is 153139140.
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 580 x 308 x 889 = 120061085760
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
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,580,308,889, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
580:2x 2x 5x 29
308:2x 2x 7x 11
889:7x 127
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 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 120061085760/(1x784)
LCM = 120061085760/784
LCM = 153139140
Thus, we can understand that the LCM of 756,580,308,889 is 153139140.
