Find LCM of 620,555,532,551,814 with Prime Factorization
| 2 | 620, 555, 532, 551, 814 |
| 2 | 310, 555, 266, 551, 407 |
| 5 | 155, 555, 133, 551, 407 |
| 19 | 31, 111, 133, 551, 407 |
| 37 | 31, 111, 7, 29, 407 |
| 31, 3, 7, 29, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 37 x 31 x 3 x 7 x 29 x 11 = 2919826140
Therefore, the lowest common multiple of 620,555,532,551,814 is 2919826140.
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.
620 x 555 x 532 x 551 x 814 = 82105511056800
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
555 : 1, 3, 5, 15, 37, 111, 185, 555
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
551 : 1, 19, 29, 551
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,555,532,551,814, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
555:3x 5x 37
532:2x 2x 7x 19
551:19x 29
814:2x 11x 37
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 19x 37 = 28120
Therefore, the value for common factors is 28120.
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 = 82105511056800/(1x28120)
LCM = 82105511056800/28120
LCM = 2919826140
Thus, we can understand that the LCM of 620,555,532,551,814 is 2919826140.
