Find LCM of 546,255,666,980 with Prime Factorization
| 2 | 546, 255, 666, 980 |
| 3 | 273, 255, 333, 490 |
| 5 | 91, 85, 111, 490 |
| 7 | 91, 17, 111, 98 |
| 13, 17, 111, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 17 x 111 x 14 = 72121140
Therefore, the lowest common multiple of 546,255,666,980 is 72121140.
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.
546 x 255 x 666 x 980 = 90872636400
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
255 : 1, 3, 5, 15, 17, 51, 85, 255
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
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 546,255,666,980, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
255:3x 5x 17
666:2x 3x 3x 37
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 90872636400/(1x1260)
LCM = 90872636400/1260
LCM = 72121140
Thus, we can understand that the LCM of 546,255,666,980 is 72121140.
