Find LCM of 721,363,550,670,231 with Prime Factorization
| 2 | 721, 363, 550, 670, 231 |
| 3 | 721, 363, 275, 335, 231 |
| 5 | 721, 121, 275, 335, 77 |
| 7 | 721, 121, 55, 67, 77 |
| 11 | 103, 121, 55, 67, 11 |
| 103, 1, 5, 67, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 103 x 1 x 5 x 67 x 11 = 876772050
Therefore, the lowest common multiple of 721,363,550,670,231 is 876772050.
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.
721 x 363 x 550 x 670 x 231 = 22278777790500
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.
721 : 1, 7, 103, 721
363 : 1, 3, 11, 33, 121, 363
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
670 : 1, 2, 5, 10, 67, 134, 335, 670
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,363,550,670,231, is 1.
Now, the common factors can be found like this.
721:7x 103
363:3x 11x 11
550:2x 5x 5x 11
670:2x 5x 67
231:3x 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 3x 5x 7x 11x 11 = 25410
Therefore, the value for common factors is 25410.
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 = 22278777790500/(1x25410)
LCM = 22278777790500/25410
LCM = 876772050
Thus, we can understand that the LCM of 721,363,550,670,231 is 876772050.
