Given numbers are 238,550,803,690,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,550,803,690,387 is 42527642850.
Find LCM of 238,550,803,690,387 with Prime Factorization
| 2 | 238, 550, 803, 690, 387 |
| 3 | 119, 275, 803, 345, 387 |
| 5 | 119, 275, 803, 115, 129 |
| 11 | 119, 55, 803, 23, 129 |
| 119, 5, 73, 23, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 119 x 5 x 73 x 23 x 129 = 42527642850
Therefore, the lowest common multiple of 238,550,803,690,387 is 42527642850.
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.
238 x 550 x 803 x 690 x 387 = 28068244281000
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
803 : 1, 11, 73, 803
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,550,803,690,387, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
550:2x 5x 5x 11
803:11x 73
690:2x 3x 5x 23
387:3x 3x 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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 28068244281000/(1x660)
LCM = 28068244281000/660
LCM = 42527642850
Thus, we can understand that the LCM of 238,550,803,690,387 is 42527642850.
