Find LCM of 574,414,645,491,820 with Prime Factorization
| 2 | 574, 414, 645, 491, 820 |
| 3 | 287, 207, 645, 491, 410 |
| 5 | 287, 69, 215, 491, 410 |
| 41 | 287, 69, 43, 491, 82 |
| 7, 69, 43, 491, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 7 x 69 x 43 x 491 x 2 = 25086044340
Therefore, the lowest common multiple of 574,414,645,491,820 is 25086044340.
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.
574 x 414 x 645 x 491 x 820 = 61711669076400
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.
574 : 1, 2, 7, 14, 41, 82, 287, 574
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
645 : 1, 3, 5, 15, 43, 129, 215, 645
491 : 1, 491
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,414,645,491,820, is 1.
Now, the common factors can be found like this.
574:2x 7x 41
414:2x 3x 3x 23
645:3x 5x 43
491:491
820:2x 2x 5x 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 2x 3x 5x 41 = 2460
Therefore, the value for common factors is 2460.
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 = 61711669076400/(1x2460)
LCM = 61711669076400/2460
LCM = 25086044340
Thus, we can understand that the LCM of 574,414,645,491,820 is 25086044340.
