Given numbers are 497,938,351,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,938,351,768 is 2992114944.
Find LCM of 497,938,351,768 with Prime Factorization
| 2 | 497, 938, 351, 768 |
| 3 | 497, 469, 351, 384 |
| 7 | 497, 469, 117, 128 |
| 71, 67, 117, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 67 x 117 x 128 = 2992114944
Therefore, the lowest common multiple of 497,938,351,768 is 2992114944.
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.
497 x 938 x 351 x 768 = 125668827648
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.
497 : 1, 7, 71, 497
938 : 1, 2, 7, 14, 67, 134, 469, 938
351 : 1, 3, 9, 13, 27, 39, 117, 351
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,938,351,768, is 1.
Now, the common factors can be found like this.
497:7x 71
938:2x 7x 67
351:3x 3x 3x 13
768:2x 2x 2x 2x 2x 2x 2x 2x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 125668827648/(1x42)
LCM = 125668827648/42
LCM = 2992114944
Thus, we can understand that the LCM of 497,938,351,768 is 2992114944.
