Find LCM of 671,342,423,836,980 with Prime Factorization
| 2 | 671, 342, 423, 836, 980 |
| 2 | 671, 171, 423, 418, 490 |
| 3 | 671, 171, 423, 209, 245 |
| 3 | 671, 57, 141, 209, 245 |
| 11 | 671, 19, 47, 209, 245 |
| 19 | 61, 19, 47, 19, 245 |
| 61, 1, 47, 1, 245 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 19 x 61 x 1 x 47 x 1 x 245 = 5284970460
Therefore, the lowest common multiple of 671,342,423,836,980 is 5284970460.
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.
671 x 342 x 423 x 836 x 980 = 79528235482080
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.
671 : 1, 11, 61, 671
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
423 : 1, 3, 9, 47, 141, 423
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,342,423,836,980, is 1.
Now, the common factors can be found like this.
671:11x 61
342:2x 3x 3x 19
423:3x 3x 47
836:2x 2x 11x 19
980:2x 2x 5x 7x 7
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 3x 3x 11x 19 = 15048
Therefore, the value for common factors is 15048.
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 = 79528235482080/(1x15048)
LCM = 79528235482080/15048
LCM = 5284970460
Thus, we can understand that the LCM of 671,342,423,836,980 is 5284970460.
