Given numbers are 398,228,588,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,228,588,636 is 117831084.
Find LCM of 398,228,588,636 with Prime Factorization
| 2 | 398, 228, 588, 636 |
| 2 | 199, 114, 294, 318 |
| 3 | 199, 57, 147, 159 |
| 199, 19, 49, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 199 x 19 x 49 x 53 = 117831084
Therefore, the lowest common multiple of 398,228,588,636 is 117831084.
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.
398 x 228 x 588 x 636 = 33935352192
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.
398 : 1, 2, 199, 398
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,228,588,636, is 2.
Now, the common factors can be found like this.
398:2x 199
228:2x 2x 3x 19
588:2x 2x 3x 7x 7
636:2x 2x 3x 53
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 33935352192/(2x144)
LCM = 33935352192/288
LCM = 117831084
Thus, we can understand that the LCM of 398,228,588,636 is 117831084.
