Given numbers are 769,156,794,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,156,794,162 is 1285894116.
Find LCM of 769,156,794,162 with Prime Factorization
| 2 | 769, 156, 794, 162 |
| 3 | 769, 78, 397, 81 |
| 769, 26, 397, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 769 x 26 x 397 x 27 = 1285894116
Therefore, the lowest common multiple of 769,156,794,162 is 1285894116.
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.
769 x 156 x 794 x 162 = 15430729392
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.
769 : 1, 769
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
794 : 1, 2, 397, 794
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,156,794,162, is 1.
Now, the common factors can be found like this.
769:769
156:2x 2x 3x 13
794:2x 397
162:2x 3x 3x 3x 3
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 3 = 12
Therefore, the value for common factors is 12.
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 = 15430729392/(1x12)
LCM = 15430729392/12
LCM = 1285894116
Thus, we can understand that the LCM of 769,156,794,162 is 1285894116.
