Given numbers are 698,639,142,233
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,639,142,233 is 103923126.
Find LCM of 698,639,142,233 with Prime Factorization
| 2 | 698, 639, 142, 233 |
| 71 | 349, 639, 71, 233 |
| 349, 9, 1, 233 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 349 x 9 x 1 x 233 = 103923126
Therefore, the lowest common multiple of 698,639,142,233 is 103923126.
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.
698 x 639 x 142 x 233 = 14757083892
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.
698 : 1, 2, 349, 698
639 : 1, 3, 9, 71, 213, 639
142 : 1, 2, 71, 142
233 : 1, 233
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,639,142,233, is 1.
Now, the common factors can be found like this.
698:2x 349
639:3x 3x 71
142:2x 71
233:233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 14757083892/(1x142)
LCM = 14757083892/142
LCM = 103923126
Thus, we can understand that the LCM of 698,639,142,233 is 103923126.
