Find LCM of 890,697,660,801,220 with Prime Factorization
| 2 | 890, 697, 660, 801, 220 |
| 2 | 445, 697, 330, 801, 110 |
| 3 | 445, 697, 165, 801, 55 |
| 5 | 445, 697, 55, 267, 55 |
| 11 | 89, 697, 11, 267, 11 |
| 89 | 89, 697, 1, 267, 1 |
| 1, 697, 1, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 89 x 1 x 697 x 1 x 3 x 1 = 122825340
Therefore, the lowest common multiple of 890,697,660,801,220 is 122825340.
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.
890 x 697 x 660 x 801 x 220 = 72147604716000
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
697 : 1, 17, 41, 697
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
801 : 1, 3, 9, 89, 267, 801
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,697,660,801,220, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
697:17x 41
660:2x 2x 3x 5x 11
801:3x 3x 89
220:2x 2x 5x 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 2x 2x 3x 5x 5x 11x 89 = 587400
Therefore, the value for common factors is 587400.
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 = 72147604716000/(1x587400)
LCM = 72147604716000/587400
LCM = 122825340
Thus, we can understand that the LCM of 890,697,660,801,220 is 122825340.
