Given numbers are 399,470,836,708
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,470,836,708 is 243413940.
Find LCM of 399,470,836,708 with Prime Factorization
| 2 | 399, 470, 836, 708 |
| 2 | 399, 235, 418, 354 |
| 3 | 399, 235, 209, 177 |
| 19 | 133, 235, 209, 59 |
| 7, 235, 11, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 7 x 235 x 11 x 59 = 243413940
Therefore, the lowest common multiple of 399,470,836,708 is 243413940.
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.
399 x 470 x 836 x 708 = 110996756640
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
470 : 1, 2, 5, 10, 47, 94, 235, 470
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,470,836,708, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
470:2x 5x 47
836:2x 2x 11x 19
708:2x 2x 3x 59
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 110996756640/(1x456)
LCM = 110996756640/456
LCM = 243413940
Thus, we can understand that the LCM of 399,470,836,708 is 243413940.
