Find LCM of 785,984,129,872,773 with Prime Factorization
| 2 | 785, 984, 129, 872, 773 |
| 2 | 785, 492, 129, 436, 773 |
| 2 | 785, 246, 129, 218, 773 |
| 3 | 785, 123, 129, 109, 773 |
| 785, 41, 43, 109, 773 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 785 x 41 x 43 x 109 x 773 = 2798589514440
Therefore, the lowest common multiple of 785,984,129,872,773 is 2798589514440.
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.
785 x 984 x 129 x 872 x 773 = 67166148346560
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.
785 : 1, 5, 157, 785
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
129 : 1, 3, 43, 129
872 : 1, 2, 4, 8, 109, 218, 436, 872
773 : 1, 773
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,984,129,872,773, is 1.
Now, the common factors can be found like this.
785:5x 157
984:2x 2x 2x 3x 41
129:3x 43
872:2x 2x 2x 109
773:773
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 3 = 24
Therefore, the value for common factors is 24.
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 = 67166148346560/(1x24)
LCM = 67166148346560/24
LCM = 2798589514440
Thus, we can understand that the LCM of 785,984,129,872,773 is 2798589514440.
