Given numbers are 923,698,142,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,698,142,644 is 207449788.
Find LCM of 923,698,142,644 with Prime Factorization
| 2 | 923, 698, 142, 644 |
| 71 | 923, 349, 71, 322 |
| 13, 349, 1, 322 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 13 x 349 x 1 x 322 = 207449788
Therefore, the lowest common multiple of 923,698,142,644 is 207449788.
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.
923 x 698 x 142 x 644 = 58915739792
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.
923 : 1, 13, 71, 923
698 : 1, 2, 349, 698
142 : 1, 2, 71, 142
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,698,142,644, is 1.
Now, the common factors can be found like this.
923:13x 71
698:2x 349
142:2x 71
644:2x 2x 7x 23
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 71 = 284
Therefore, the value for common factors is 284.
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 = 58915739792/(1x284)
LCM = 58915739792/284
LCM = 207449788
Thus, we can understand that the LCM of 923,698,142,644 is 207449788.
