Find LCM of 956,644,780,994,415 with Prime Factorization
| 2 | 956, 644, 780, 994, 415 |
| 2 | 478, 322, 390, 497, 415 |
| 5 | 239, 161, 195, 497, 415 |
| 7 | 239, 161, 39, 497, 83 |
| 239, 23, 39, 71, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 239 x 23 x 39 x 71 x 83 = 176870262660
Therefore, the lowest common multiple of 956,644,780,994,415 is 176870262660.
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.
956 x 644 x 780 x 994 x 415 = 198094694179200
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.
956 : 1, 2, 4, 239, 478, 956
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
994 : 1, 2, 7, 14, 71, 142, 497, 994
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 956,644,780,994,415, is 1.
Now, the common factors can be found like this.
956:2x 2x 239
644:2x 2x 7x 23
780:2x 2x 3x 5x 13
994:2x 7x 71
415:5x 83
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 2x 2x 5x 7 = 1120
Therefore, the value for common factors is 1120.
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 = 198094694179200/(1x1120)
LCM = 198094694179200/1120
LCM = 176870262660
Thus, we can understand that the LCM of 956,644,780,994,415 is 176870262660.
