Given numbers are 176,756,771,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 176,756,771,639 is 606968208.
Find LCM of 176,756,771,639 with Prime Factorization
| 2 | 176, 756, 771, 639 |
| 2 | 88, 378, 771, 639 |
| 3 | 44, 189, 771, 639 |
| 3 | 44, 63, 257, 213 |
| 44, 21, 257, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 44 x 21 x 257 x 71 = 606968208
Therefore, the lowest common multiple of 176,756,771,639 is 606968208.
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.
176 x 756 x 771 x 639 = 65552566464
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.
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
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
771 : 1, 3, 257, 771
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 176,756,771,639, is 1.
Now, the common factors can be found like this.
176:2x 2x 2x 2x 11
756:2x 2x 3x 3x 3x 7
771:3x 257
639:3x 3x 71
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 = 65552566464/(1x108)
LCM = 65552566464/108
LCM = 606968208
Thus, we can understand that the LCM of 176,756,771,639 is 606968208.
