Given numbers are 273,621,680,610,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 273,621,680,610,646 is 44537449320.
Find LCM of 273,621,680,610,646 with Prime Factorization
| 2 | 273, 621, 680, 610, 646 |
| 3 | 273, 621, 340, 305, 323 |
| 5 | 91, 207, 340, 305, 323 |
| 17 | 91, 207, 68, 61, 323 |
| 91, 207, 4, 61, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 91 x 207 x 4 x 61 x 19 = 44537449320
Therefore, the lowest common multiple of 273,621,680,610,646 is 44537449320.
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.
273 x 621 x 680 x 610 x 646 = 45428198306400
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
621 : 1, 3, 9, 23, 27, 69, 207, 621
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
610 : 1, 2, 5, 10, 61, 122, 305, 610
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,621,680,610,646, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
621:3x 3x 3x 23
680:2x 2x 2x 5x 17
610:2x 5x 61
646:2x 17x 19
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 5x 17 = 1020
Therefore, the value for common factors is 1020.
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 = 45428198306400/(1x1020)
LCM = 45428198306400/1020
LCM = 44537449320
Thus, we can understand that the LCM of 273,621,680,610,646 is 44537449320.
