Given numbers are 347,827,729,840,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,827,729,840,973 is 8142079606920.
Find LCM of 347,827,729,840,973 with Prime Factorization
| 3 | 347, 827, 729, 840, 973 |
| 7 | 347, 827, 243, 280, 973 |
| 347, 827, 243, 40, 139 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 347 x 827 x 243 x 40 x 139 = 8142079606920
Therefore, the lowest common multiple of 347,827,729,840,973 is 8142079606920.
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.
347 x 827 x 729 x 840 x 973 = 170983671745320
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.
347 : 1, 347
827 : 1, 827
729 : 1, 3, 9, 27, 81, 243, 729
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,827,729,840,973, is 1.
Now, the common factors can be found like this.
347:347
827:827
729:3x 3x 3x 3x 3x 3
840:2x 2x 2x 3x 5x 7
973:7x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 170983671745320/(1x21)
LCM = 170983671745320/21
LCM = 8142079606920
Thus, we can understand that the LCM of 347,827,729,840,973 is 8142079606920.
