Given numbers are 781,852,390,155,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,852,390,155,164 is 774267780.
Find LCM of 781,852,390,155,164 with Prime Factorization
| 2 | 781, 852, 390, 155, 164 |
| 2 | 781, 426, 195, 155, 82 |
| 3 | 781, 213, 195, 155, 41 |
| 5 | 781, 71, 65, 155, 41 |
| 71 | 781, 71, 13, 31, 41 |
| 11, 1, 13, 31, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 71 x 11 x 1 x 13 x 31 x 41 = 774267780
Therefore, the lowest common multiple of 781,852,390,155,164 is 774267780.
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.
781 x 852 x 390 x 155 x 164 = 6596761485600
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.
781 : 1, 11, 71, 781
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
155 : 1, 5, 31, 155
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,852,390,155,164, is 1.
Now, the common factors can be found like this.
781:11x 71
852:2x 2x 3x 71
390:2x 3x 5x 13
155:5x 31
164:2x 2x 41
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 3x 5x 71 = 8520
Therefore, the value for common factors is 8520.
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 = 6596761485600/(1x8520)
LCM = 6596761485600/8520
LCM = 774267780
Thus, we can understand that the LCM of 781,852,390,155,164 is 774267780.
