Given numbers are 533,456,743,861,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 533,456,743,861,643 is 812811572664.
Find LCM of 533,456,743,861,643 with Prime Factorization
| 3 | 533, 456, 743, 861, 643 |
| 41 | 533, 152, 743, 287, 643 |
| 13, 152, 743, 7, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 13 x 152 x 743 x 7 x 643 = 812811572664
Therefore, the lowest common multiple of 533,456,743,861,643 is 812811572664.
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.
533 x 456 x 743 x 861 x 643 = 99975823437672
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.
533 : 1, 13, 41, 533
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
743 : 1, 743
861 : 1, 3, 7, 21, 41, 123, 287, 861
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 533,456,743,861,643, is 1.
Now, the common factors can be found like this.
533:13x 41
456:2x 2x 2x 3x 19
743:743
861:3x 7x 41
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 99975823437672/(1x123)
LCM = 99975823437672/123
LCM = 812811572664
Thus, we can understand that the LCM of 533,456,743,861,643 is 812811572664.
