Given numbers are 143,756,611,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,756,611,662 is 1681836156.
Find LCM of 143,756,611,662 with Prime Factorization
| 2 | 143, 756, 611, 662 |
| 13 | 143, 378, 611, 331 |
| 11, 378, 47, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 11 x 378 x 47 x 331 = 1681836156
Therefore, the lowest common multiple of 143,756,611,662 is 1681836156.
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.
143 x 756 x 611 x 662 = 43727740056
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.
143 : 1, 11, 13, 143
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
611 : 1, 13, 47, 611
662 : 1, 2, 331, 662
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,756,611,662, is 1.
Now, the common factors can be found like this.
143:11x 13
756:2x 2x 3x 3x 3x 7
611:13x 47
662:2x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 43727740056/(1x26)
LCM = 43727740056/26
LCM = 1681836156
Thus, we can understand that the LCM of 143,756,611,662 is 1681836156.
