Given numbers are 301,980,649,387,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 301,980,649,387,688 is 984558960.
Find LCM of 301,980,649,387,688 with Prime Factorization
| 2 | 301, 980, 649, 387, 688 |
| 2 | 301, 490, 649, 387, 344 |
| 7 | 301, 245, 649, 387, 172 |
| 43 | 43, 35, 649, 387, 172 |
| 1, 35, 649, 9, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 43 x 1 x 35 x 649 x 9 x 4 = 984558960
Therefore, the lowest common multiple of 301,980,649,387,688 is 984558960.
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.
301 x 980 x 649 x 387 x 688 = 50972586477120
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.
301 : 1, 7, 43, 301
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
649 : 1, 11, 59, 649
387 : 1, 3, 9, 43, 129, 387
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 301,980,649,387,688, is 1.
Now, the common factors can be found like this.
301:7x 43
980:2x 2x 5x 7x 7
649:11x 59
387:3x 3x 43
688:2x 2x 2x 2x 43
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 7x 43x 43 = 51772
Therefore, the value for common factors is 51772.
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 = 50972586477120/(1x51772)
LCM = 50972586477120/51772
LCM = 984558960
Thus, we can understand that the LCM of 301,980,649,387,688 is 984558960.
