Find LCM of 479,253,160,520,391 with Prime Factorization
2 | 479, 253, 160, 520, 391 |
2 | 479, 253, 80, 260, 391 |
2 | 479, 253, 40, 130, 391 |
5 | 479, 253, 20, 65, 391 |
23 | 479, 253, 4, 13, 391 |
479, 11, 4, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 479 x 11 x 4 x 13 x 17 = 4285172320
Therefore, the lowest common multiple of 479,253,160,520,391 is 4285172320.
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.
479 x 253 x 160 x 520 x 391 = 3942358534400
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.
479 : 1, 479
253 : 1, 11, 23, 253
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,253,160,520,391, is 1.
Now, the common factors can be found like this.
479:479
253:11x 23
160:2x 2x 2x 2x 2x 5
520:2x 2x 2x 5x 13
391:17x 23
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 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 3942358534400/(1x920)
LCM = 3942358534400/920
LCM = 4285172320
Thus, we can understand that the LCM of 479,253,160,520,391 is 4285172320.
