Find LCM of 549,429,273,780,770 with Prime Factorization
| 2 | 549, 429, 273, 780, 770 |
| 3 | 549, 429, 273, 390, 385 |
| 5 | 183, 143, 91, 130, 385 |
| 7 | 183, 143, 91, 26, 77 |
| 11 | 183, 143, 13, 26, 11 |
| 13 | 183, 13, 13, 26, 1 |
| 183, 1, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 13 x 183 x 1 x 1 x 2 x 1 = 10990980
Therefore, the lowest common multiple of 549,429,273,780,770 is 10990980.
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.
549 x 429 x 273 x 780 x 770 = 38616918139800
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.
549 : 1, 3, 9, 61, 183, 549
429 : 1, 3, 11, 13, 33, 39, 143, 429
273 : 1, 3, 7, 13, 21, 39, 91, 273
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
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 549,429,273,780,770, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
429:3x 11x 13
273:3x 7x 13
780:2x 2x 3x 5x 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 3x 3x 3x 5x 7x 11x 13x 13 = 3513510
Therefore, the value for common factors is 3513510.
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 = 38616918139800/(1x3513510)
LCM = 38616918139800/3513510
LCM = 10990980
Thus, we can understand that the LCM of 549,429,273,780,770 is 10990980.
