Find LCM of 707,484,715,770 with Prime Factorization
| 2 | 707, 484, 715, 770 |
| 5 | 707, 242, 715, 385 |
| 7 | 707, 242, 143, 77 |
| 11 | 101, 242, 143, 11 |
| 101, 22, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 101 x 22 x 13 x 1 = 22242220
Therefore, the lowest common multiple of 707,484,715,770 is 22242220.
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.
707 x 484 x 715 x 770 = 188391603400
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.
707 : 1, 7, 101, 707
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
715 : 1, 5, 11, 13, 55, 65, 143, 715
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,484,715,770, is 1.
Now, the common factors can be found like this.
707:7x 101
484:2x 2x 11x 11
715:5x 11x 13
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 11x 11 = 8470
Therefore, the value for common factors is 8470.
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 = 188391603400/(1x8470)
LCM = 188391603400/8470
LCM = 22242220
Thus, we can understand that the LCM of 707,484,715,770 is 22242220.
