Given numbers are 671,562,806,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,562,806,378 is 28722728034.
Find LCM of 671,562,806,378 with Prime Factorization
| 2 | 671, 562, 806, 378 |
| 671, 281, 403, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 671 x 281 x 403 x 189 = 28722728034
Therefore, the lowest common multiple of 671,562,806,378 is 28722728034.
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.
671 x 562 x 806 x 378 = 114890912136
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.
671 : 1, 11, 61, 671
562 : 1, 2, 281, 562
806 : 1, 2, 13, 26, 31, 62, 403, 806
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,562,806,378, is 1.
Now, the common factors can be found like this.
671:11x 61
562:2x 281
806:2x 13x 31
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 114890912136/(1x4)
LCM = 114890912136/4
LCM = 28722728034
Thus, we can understand that the LCM of 671,562,806,378 is 28722728034.
