Given numbers are 838,374,399,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,374,399,697 is 2563553454.
Find LCM of 838,374,399,697 with Prime Factorization
| 2 | 838, 374, 399, 697 |
| 17 | 419, 187, 399, 697 |
| 419, 11, 399, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 419 x 11 x 399 x 41 = 2563553454
Therefore, the lowest common multiple of 838,374,399,697 is 2563553454.
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.
838 x 374 x 399 x 697 = 87160817436
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.
838 : 1, 2, 419, 838
374 : 1, 2, 11, 17, 22, 34, 187, 374
399 : 1, 3, 7, 19, 21, 57, 133, 399
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,374,399,697, is 1.
Now, the common factors can be found like this.
838:2x 419
374:2x 11x 17
399:3x 7x 19
697:17x 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 17 = 34
Therefore, the value for common factors is 34.
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 = 87160817436/(1x34)
LCM = 87160817436/34
LCM = 2563553454
Thus, we can understand that the LCM of 838,374,399,697 is 2563553454.
