Given numbers are 423,357,255,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,357,255,971 is 244386135.
Find LCM of 423,357,255,971 with Prime Factorization
| 3 | 423, 357, 255, 971 |
| 17 | 141, 119, 85, 971 |
| 141, 7, 5, 971 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 141 x 7 x 5 x 971 = 244386135
Therefore, the lowest common multiple of 423,357,255,971 is 244386135.
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.
423 x 357 x 255 x 971 = 37391078655
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.
423 : 1, 3, 9, 47, 141, 423
357 : 1, 3, 7, 17, 21, 51, 119, 357
255 : 1, 3, 5, 15, 17, 51, 85, 255
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,357,255,971, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
357:3x 7x 17
255:3x 5x 17
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 37391078655/(1x153)
LCM = 37391078655/153
LCM = 244386135
Thus, we can understand that the LCM of 423,357,255,971 is 244386135.
