Find LCM of 787,928,124,744,621 with Prime Factorization
2 | 787, 928, 124, 744, 621 |
2 | 787, 464, 62, 372, 621 |
2 | 787, 232, 31, 186, 621 |
3 | 787, 116, 31, 93, 621 |
31 | 787, 116, 31, 31, 207 |
787, 116, 1, 1, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 31 x 787 x 116 x 1 x 1 x 207 = 14059698336
Therefore, the lowest common multiple of 787,928,124,744,621 is 14059698336.
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.
787 x 928 x 124 x 744 x 621 = 41841662247936
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.
787 : 1, 787
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
124 : 1, 2, 4, 31, 62, 124
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,928,124,744,621, is 1.
Now, the common factors can be found like this.
787:787
928:2x 2x 2x 2x 2x 29
124:2x 2x 31
744:2x 2x 2x 3x 31
621:3x 3x 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 2x 2x 3x 31 = 2976
Therefore, the value for common factors is 2976.
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 = 41841662247936/(1x2976)
LCM = 41841662247936/2976
LCM = 14059698336
Thus, we can understand that the LCM of 787,928,124,744,621 is 14059698336.
