Given numbers are 759,649,561,924
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 759,649,561,924 is 21315756.
Find LCM of 759,649,561,924 with Prime Factorization
| 3 | 759, 649, 561, 924 |
| 11 | 253, 649, 187, 308 |
| 23, 59, 17, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 59 x 17 x 28 = 21315756
Therefore, the lowest common multiple of 759,649,561,924 is 21315756.
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.
759 x 649 x 561 x 924 = 255341441124
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.
759 : 1, 3, 11, 23, 33, 69, 253, 759
649 : 1, 11, 59, 649
561 : 1, 3, 11, 17, 33, 51, 187, 561
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 759,649,561,924, is 11.
Now, the common factors can be found like this.
759:3x 11x 23
649:11x 59
561:3x 11x 17
924:2x 2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 255341441124/(11x1089)
LCM = 255341441124/11979
LCM = 21315756
Thus, we can understand that the LCM of 759,649,561,924 is 21315756.
