Given numbers are 774,398,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,398,697 is 107356122.
Find LCM of 774,398,697 with Prime Factorization
| 2 | 774, 398, 697 |
| 387, 199, 697 |
Multiply the prime numbers at the bottom and the left side.
2 x 387 x 199 x 697 = 107356122
Therefore, the lowest common multiple of 774,398,697 is 107356122.
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.
774 x 398 x 697 = 214712244
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
398 : 1, 2, 199, 398
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,398,697, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
398:2x 199
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 214712244/(1x2)
LCM = 214712244/2
LCM = 107356122
Thus, we can understand that the LCM of 774,398,697 is 107356122.
