Given numbers are 964,868,692,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 964,868,692,138 is 2497077156.
Find LCM of 964,868,692,138 with Prime Factorization
| 2 | 964, 868, 692, 138 |
| 2 | 482, 434, 346, 69 |
| 241, 217, 173, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 241 x 217 x 173 x 69 = 2497077156
Therefore, the lowest common multiple of 964,868,692,138 is 2497077156.
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.
964 x 868 x 692 x 138 = 79906468992
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.
964 : 1, 2, 4, 241, 482, 964
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
692 : 1, 2, 4, 173, 346, 692
138 : 1, 2, 3, 6, 23, 46, 69, 138
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,868,692,138, is 2.
Now, the common factors can be found like this.
964:2x 2x 241
868:2x 2x 7x 31
692:2x 2x 173
138:2x 3x 23
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 2 = 16
Therefore, the value for common factors is 16.
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 = 79906468992/(2x16)
LCM = 79906468992/32
LCM = 2497077156
Thus, we can understand that the LCM of 964,868,692,138 is 2497077156.
