Given numbers are 642,690,314,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,690,314,107 is 11591310.
Find LCM of 642,690,314,107 with Prime Factorization
| 2 | 642, 690, 314, 107 |
| 3 | 321, 345, 157, 107 |
| 107 | 107, 115, 157, 107 |
| 1, 115, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 1 x 115 x 157 x 1 = 11591310
Therefore, the lowest common multiple of 642,690,314,107 is 11591310.
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.
642 x 690 x 314 x 107 = 14883242040
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
314 : 1, 2, 157, 314
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,690,314,107, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
690:2x 3x 5x 23
314:2x 157
107:107
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 107 = 1284
Therefore, the value for common factors is 1284.
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 = 14883242040/(1x1284)
LCM = 14883242040/1284
LCM = 11591310
Thus, we can understand that the LCM of 642,690,314,107 is 11591310.
