Given numbers are 697,286,822,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,286,822,225 is 6144717150.
Find LCM of 697,286,822,225 with Prime Factorization
| 2 | 697, 286, 822, 225 |
| 3 | 697, 143, 411, 225 |
| 697, 143, 137, 75 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 697 x 143 x 137 x 75 = 6144717150
Therefore, the lowest common multiple of 697,286,822,225 is 6144717150.
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.
697 x 286 x 822 x 225 = 36868302900
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.
697 : 1, 17, 41, 697
286 : 1, 2, 11, 13, 22, 26, 143, 286
822 : 1, 2, 3, 6, 137, 274, 411, 822
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,286,822,225, is 1.
Now, the common factors can be found like this.
697:17x 41
286:2x 11x 13
822:2x 3x 137
225:3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 36868302900/(1x6)
LCM = 36868302900/6
LCM = 6144717150
Thus, we can understand that the LCM of 697,286,822,225 is 6144717150.
