Given numbers are 781,464,880,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,464,880,736 is 83348320.
Find LCM of 781,464,880,736 with Prime Factorization
| 2 | 781, 464, 880, 736 |
| 2 | 781, 232, 440, 368 |
| 2 | 781, 116, 220, 184 |
| 2 | 781, 58, 110, 92 |
| 11 | 781, 29, 55, 46 |
| 71, 29, 5, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 71 x 29 x 5 x 46 = 83348320
Therefore, the lowest common multiple of 781,464,880,736 is 83348320.
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 464 x 880 x 736 = 234708869120
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
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,464,880,736, is 1.
Now, the common factors can be found like this.
781:11x 71
464:2x 2x 2x 2x 29
880:2x 2x 2x 2x 5x 11
736:2x 2x 2x 2x 2x 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 2x 2x 2x 11 = 2816
Therefore, the value for common factors is 2816.
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 = 234708869120/(1x2816)
LCM = 234708869120/2816
LCM = 83348320
Thus, we can understand that the LCM of 781,464,880,736 is 83348320.
