Given numbers are 369,838,456,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 369,838,456,697 is 399514824.
Find LCM of 369,838,456,697 with Prime Factorization
| 2 | 369, 838, 456, 697 |
| 3 | 369, 419, 228, 697 |
| 41 | 123, 419, 76, 697 |
| 3, 419, 76, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 3 x 419 x 76 x 17 = 399514824
Therefore, the lowest common multiple of 369,838,456,697 is 399514824.
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.
369 x 838 x 456 x 697 = 98280646704
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.
369 : 1, 3, 9, 41, 123, 369
838 : 1, 2, 419, 838
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,838,456,697, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
838:2x 419
456:2x 2x 2x 3x 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 3x 41 = 246
Therefore, the value for common factors is 246.
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 = 98280646704/(1x246)
LCM = 98280646704/246
LCM = 399514824
Thus, we can understand that the LCM of 369,838,456,697 is 399514824.
