Given numbers are 924,921,406,509,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 924,921,406,509,767 is 3211600307916.
Find LCM of 924,921,406,509,767 with Prime Factorization
| 2 | 924, 921, 406, 509, 767 |
| 3 | 462, 921, 203, 509, 767 |
| 7 | 154, 307, 203, 509, 767 |
| 22, 307, 29, 509, 767 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 22 x 307 x 29 x 509 x 767 = 3211600307916
Therefore, the lowest common multiple of 924,921,406,509,767 is 3211600307916.
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.
924 x 921 x 406 x 509 x 767 = 134887212932472
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.
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
921 : 1, 3, 307, 921
406 : 1, 2, 7, 14, 29, 58, 203, 406
509 : 1, 509
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,921,406,509,767, is 1.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
921:3x 307
406:2x 7x 29
509:509
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 134887212932472/(1x42)
LCM = 134887212932472/42
LCM = 3211600307916
Thus, we can understand that the LCM of 924,921,406,509,767 is 3211600307916.
