Given numbers are 946,730,781,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,730,781,772 is 9463017740.
Find LCM of 946,730,781,772 with Prime Factorization
| 2 | 946, 730, 781, 772 |
| 11 | 473, 365, 781, 386 |
| 43, 365, 71, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 43 x 365 x 71 x 386 = 9463017740
Therefore, the lowest common multiple of 946,730,781,772 is 9463017740.
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.
946 x 730 x 781 x 772 = 416372780560
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
730 : 1, 2, 5, 10, 73, 146, 365, 730
781 : 1, 11, 71, 781
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,730,781,772, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
730:2x 5x 73
781:11x 71
772:2x 2x 193
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 11 = 44
Therefore, the value for common factors is 44.
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 = 416372780560/(1x44)
LCM = 416372780560/44
LCM = 9463017740
Thus, we can understand that the LCM of 946,730,781,772 is 9463017740.
