Given numbers are 749,921,199,597
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,921,199,597 is 137275971.
Find LCM of 749,921,199,597 with Prime Factorization
| 3 | 749, 921, 199, 597 |
| 199 | 749, 307, 199, 199 |
| 749, 307, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 199 x 749 x 307 x 1 x 1 = 137275971
Therefore, the lowest common multiple of 749,921,199,597 is 137275971.
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.
749 x 921 x 199 x 597 = 81953754687
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.
749 : 1, 7, 107, 749
921 : 1, 3, 307, 921
199 : 1, 199
597 : 1, 3, 199, 597
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,921,199,597, is 1.
Now, the common factors can be found like this.
749:7x 107
921:3x 307
199:199
597:3x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 199 = 597
Therefore, the value for common factors is 597.
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 = 81953754687/(1x597)
LCM = 81953754687/597
LCM = 137275971
Thus, we can understand that the LCM of 749,921,199,597 is 137275971.
