Given numbers are 395,971,836,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 395,971,836,144 is 11543170320.
Find LCM of 395,971,836,144 with Prime Factorization
| 2 | 395, 971, 836, 144 |
| 2 | 395, 971, 418, 72 |
| 395, 971, 209, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 395 x 971 x 209 x 36 = 11543170320
Therefore, the lowest common multiple of 395,971,836,144 is 11543170320.
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.
395 x 971 x 836 x 144 = 46172681280
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.
395 : 1, 5, 79, 395
971 : 1, 971
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,971,836,144, is 1.
Now, the common factors can be found like this.
395:5x 79
971:971
836:2x 2x 11x 19
144:2x 2x 2x 2x 3x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 46172681280/(1x4)
LCM = 46172681280/4
LCM = 11543170320
Thus, we can understand that the LCM of 395,971,836,144 is 11543170320.
