Given numbers are 398,980,974,168,633
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,980,974,168,633 is 120238020840.
Find LCM of 398,980,974,168,633 with Prime Factorization
| 2 | 398, 980, 974, 168, 633 |
| 2 | 199, 490, 487, 84, 633 |
| 3 | 199, 245, 487, 42, 633 |
| 7 | 199, 245, 487, 14, 211 |
| 199, 35, 487, 2, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 199 x 35 x 487 x 2 x 211 = 120238020840
Therefore, the lowest common multiple of 398,980,974,168,633 is 120238020840.
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 980 x 974 x 168 x 633 = 40399975002240
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
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
974 : 1, 2, 487, 974
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
633 : 1, 3, 211, 633
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,980,974,168,633, is 1.
Now, the common factors can be found like this.
398:2x 199
980:2x 2x 5x 7x 7
974:2x 487
168:2x 2x 2x 3x 7
633:3x 211
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 7 = 336
Therefore, the value for common factors is 336.
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 = 40399975002240/(1x336)
LCM = 40399975002240/336
LCM = 120238020840
Thus, we can understand that the LCM of 398,980,974,168,633 is 120238020840.
