Given numbers are 964,912,621,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 964,912,621,402 is 3048295248.
Find LCM of 964,912,621,402 with Prime Factorization
| 2 | 964, 912, 621, 402 |
| 2 | 482, 456, 621, 201 |
| 3 | 241, 228, 621, 201 |
| 241, 76, 207, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 241 x 76 x 207 x 67 = 3048295248
Therefore, the lowest common multiple of 964,912,621,402 is 3048295248.
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 912 x 621 x 402 = 219477257856
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
621 : 1, 3, 9, 23, 27, 69, 207, 621
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,912,621,402, is 1.
Now, the common factors can be found like this.
964:2x 2x 241
912:2x 2x 2x 2x 3x 19
621:3x 3x 3x 23
402:2x 3x 67
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 219477257856/(1x72)
LCM = 219477257856/72
LCM = 3048295248
Thus, we can understand that the LCM of 964,912,621,402 is 3048295248.
