Find LCM of 454,702,715,561,780 with Prime Factorization
| 2 | 454, 702, 715, 561, 780 |
| 3 | 227, 351, 715, 561, 390 |
| 5 | 227, 117, 715, 187, 130 |
| 11 | 227, 117, 143, 187, 26 |
| 13 | 227, 117, 13, 17, 26 |
| 227, 9, 1, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 227 x 9 x 1 x 17 x 2 = 297991980
Therefore, the lowest common multiple of 454,702,715,561,780 is 297991980.
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.
454 x 702 x 715 x 561 x 780 = 99714076347600
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.
454 : 1, 2, 227, 454
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
715 : 1, 5, 11, 13, 55, 65, 143, 715
561 : 1, 3, 11, 17, 33, 51, 187, 561
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,702,715,561,780, is 1.
Now, the common factors can be found like this.
454:2x 227
702:2x 3x 3x 3x 13
715:5x 11x 13
561:3x 11x 17
780:2x 2x 3x 5x 13
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 3x 5x 11x 13x 13 = 334620
Therefore, the value for common factors is 334620.
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 = 99714076347600/(1x334620)
LCM = 99714076347600/334620
LCM = 297991980
Thus, we can understand that the LCM of 454,702,715,561,780 is 297991980.
