Given numbers are 723,688,572,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,688,572,892 is 15862353936.
Find LCM of 723,688,572,892 with Prime Factorization
| 2 | 723, 688, 572, 892 |
| 2 | 723, 344, 286, 446 |
| 723, 172, 143, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 723 x 172 x 143 x 223 = 15862353936
Therefore, the lowest common multiple of 723,688,572,892 is 15862353936.
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.
723 x 688 x 572 x 892 = 253797662976
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.
723 : 1, 3, 241, 723
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,688,572,892, is 1.
Now, the common factors can be found like this.
723:3x 241
688:2x 2x 2x 2x 43
572:2x 2x 11x 13
892:2x 2x 223
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 253797662976/(1x16)
LCM = 253797662976/16
LCM = 15862353936
Thus, we can understand that the LCM of 723,688,572,892 is 15862353936.
