Given numbers are 756,311,583,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,311,583,154 is 137072628.
Find LCM of 756,311,583,154 with Prime Factorization
2 | 756, 311, 583, 154 |
7 | 378, 311, 583, 77 |
11 | 54, 311, 583, 11 |
54, 311, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 54 x 311 x 53 x 1 = 137072628
Therefore, the lowest common multiple of 756,311,583,154 is 137072628.
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 311 x 583 x 154 = 21109184712
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
311 : 1, 311
583 : 1, 11, 53, 583
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,311,583,154, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
311:311
583:11x 53
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 21109184712/(1x154)
LCM = 21109184712/154
LCM = 137072628
Thus, we can understand that the LCM of 756,311,583,154 is 137072628.
