Find LCM of 940,651,520,387,923 with Prime Factorization
| 2 | 940, 651, 520, 387, 923 |
| 2 | 470, 651, 260, 387, 923 |
| 3 | 235, 651, 130, 387, 923 |
| 5 | 235, 217, 130, 129, 923 |
| 13 | 47, 217, 26, 129, 923 |
| 47, 217, 2, 129, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 47 x 217 x 2 x 129 x 71 = 145723719960
Therefore, the lowest common multiple of 940,651,520,387,923 is 145723719960.
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.
940 x 651 x 520 x 387 x 923 = 113664501568800
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
651 : 1, 3, 7, 21, 31, 93, 217, 651
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
387 : 1, 3, 9, 43, 129, 387
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,651,520,387,923, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
651:3x 7x 31
520:2x 2x 2x 5x 13
387:3x 3x 43
923:13x 71
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 113664501568800/(1x780)
LCM = 113664501568800/780
LCM = 145723719960
Thus, we can understand that the LCM of 940,651,520,387,923 is 145723719960.
