Given numbers are 781,506,692,485,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,506,692,485,844 is 1272064574660.
Find LCM of 781,506,692,485,844 with Prime Factorization
| 2 | 781, 506, 692, 485, 844 |
| 2 | 781, 253, 346, 485, 422 |
| 11 | 781, 253, 173, 485, 211 |
| 71, 23, 173, 485, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 71 x 23 x 173 x 485 x 211 = 1272064574660
Therefore, the lowest common multiple of 781,506,692,485,844 is 1272064574660.
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 506 x 692 x 485 x 844 = 111941682570080
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
506 : 1, 2, 11, 22, 23, 46, 253, 506
692 : 1, 2, 4, 173, 346, 692
485 : 1, 5, 97, 485
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,506,692,485,844, is 1.
Now, the common factors can be found like this.
781:11x 71
506:2x 11x 23
692:2x 2x 173
485:5x 97
844:2x 2x 211
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 11 = 88
Therefore, the value for common factors is 88.
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 = 111941682570080/(1x88)
LCM = 111941682570080/88
LCM = 1272064574660
Thus, we can understand that the LCM of 781,506,692,485,844 is 1272064574660.
