Given numbers are 643,534,744,310,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,534,744,310,370 is 7876724280.
Find LCM of 643,534,744,310,370 with Prime Factorization
| 2 | 643, 534, 744, 310, 370 |
| 3 | 643, 267, 372, 155, 185 |
| 5 | 643, 89, 124, 155, 185 |
| 31 | 643, 89, 124, 31, 37 |
| 643, 89, 4, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 643 x 89 x 4 x 1 x 37 = 7876724280
Therefore, the lowest common multiple of 643,534,744,310,370 is 7876724280.
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.
643 x 534 x 744 x 310 x 370 = 29301414321600
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.
643 : 1, 643
534 : 1, 2, 3, 6, 89, 178, 267, 534
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
310 : 1, 2, 5, 10, 31, 62, 155, 310
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,534,744,310,370, is 1.
Now, the common factors can be found like this.
643:643
534:2x 3x 89
744:2x 2x 2x 3x 31
310:2x 5x 31
370:2x 5x 37
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 3x 5x 31 = 3720
Therefore, the value for common factors is 3720.
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 = 29301414321600/(1x3720)
LCM = 29301414321600/3720
LCM = 7876724280
Thus, we can understand that the LCM of 643,534,744,310,370 is 7876724280.
