Find LCM of 210,707,391,962,460 with Prime Factorization
| 2 | 210, 707, 391, 962, 460 |
| 5 | 105, 707, 391, 481, 230 |
| 7 | 21, 707, 391, 481, 46 |
| 23 | 3, 101, 391, 481, 46 |
| 3, 101, 17, 481, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 3 x 101 x 17 x 481 x 2 = 7977971820
Therefore, the lowest common multiple of 210,707,391,962,460 is 7977971820.
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.
210 x 707 x 391 x 962 x 460 = 25689069260400
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
707 : 1, 7, 101, 707
391 : 1, 17, 23, 391
962 : 1, 2, 13, 26, 37, 74, 481, 962
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,707,391,962,460, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
707:7x 101
391:17x 23
962:2x 13x 37
460:2x 2x 5x 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 5x 7x 23 = 3220
Therefore, the value for common factors is 3220.
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 = 25689069260400/(1x3220)
LCM = 25689069260400/3220
LCM = 7977971820
Thus, we can understand that the LCM of 210,707,391,962,460 is 7977971820.
