Given numbers are 781,218,944,495,547
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,218,944,495,547 is 1978105116240.
Find LCM of 781,218,944,495,547 with Prime Factorization
| 2 | 781, 218, 944, 495, 547 |
| 11 | 781, 109, 472, 495, 547 |
| 71, 109, 472, 45, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 109 x 472 x 45 x 547 = 1978105116240
Therefore, the lowest common multiple of 781,218,944,495,547 is 1978105116240.
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 218 x 944 x 495 x 547 = 43518312557280
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
218 : 1, 2, 109, 218
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,218,944,495,547, is 1.
Now, the common factors can be found like this.
781:11x 71
218:2x 109
944:2x 2x 2x 2x 59
495:3x 3x 5x 11
547:547
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 43518312557280/(1x22)
LCM = 43518312557280/22
LCM = 1978105116240
Thus, we can understand that the LCM of 781,218,944,495,547 is 1978105116240.
