Given numbers are 310,736,643,314,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,736,643,314,690 is 34549470240.
Find LCM of 310,736,643,314,690 with Prime Factorization
| 2 | 310, 736, 643, 314, 690 |
| 5 | 155, 368, 643, 157, 345 |
| 23 | 31, 368, 643, 157, 69 |
| 31, 16, 643, 157, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 31 x 16 x 643 x 157 x 3 = 34549470240
Therefore, the lowest common multiple of 310,736,643,314,690 is 34549470240.
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.
310 x 736 x 643 x 314 x 690 = 31785512620800
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
643 : 1, 643
314 : 1, 2, 157, 314
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,736,643,314,690, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
736:2x 2x 2x 2x 2x 23
643:643
314:2x 157
690:2x 3x 5x 23
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 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 31785512620800/(1x920)
LCM = 31785512620800/920
LCM = 34549470240
Thus, we can understand that the LCM of 310,736,643,314,690 is 34549470240.
