Given numbers are 479,308,670,221,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 479,308,670,221,693 is 98302784580.
Find LCM of 479,308,670,221,693 with Prime Factorization
| 2 | 479, 308, 670, 221, 693 |
| 7 | 479, 154, 335, 221, 693 |
| 11 | 479, 22, 335, 221, 99 |
| 479, 2, 335, 221, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 479 x 2 x 335 x 221 x 9 = 98302784580
Therefore, the lowest common multiple of 479,308,670,221,693 is 98302784580.
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.
479 x 308 x 670 x 221 x 693 = 15138628825320
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.
479 : 1, 479
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
670 : 1, 2, 5, 10, 67, 134, 335, 670
221 : 1, 13, 17, 221
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,308,670,221,693, is 1.
Now, the common factors can be found like this.
479:479
308:2x 2x 7x 11
670:2x 5x 67
221:13x 17
693:3x 3x 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 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 15138628825320/(1x154)
LCM = 15138628825320/154
LCM = 98302784580
Thus, we can understand that the LCM of 479,308,670,221,693 is 98302784580.
