Given numbers are 715,351,749,973,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,351,749,973,946 is 172848205530.
Find LCM of 715,351,749,973,946 with Prime Factorization
| 7 | 715, 351, 749, 973, 946 |
| 11 | 715, 351, 107, 139, 946 |
| 13 | 65, 351, 107, 139, 86 |
| 5, 27, 107, 139, 86 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 13 x 5 x 27 x 107 x 139 x 86 = 172848205530
Therefore, the lowest common multiple of 715,351,749,973,946 is 172848205530.
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.
715 x 351 x 749 x 973 x 946 = 173021053735530
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
351 : 1, 3, 9, 13, 27, 39, 117, 351
749 : 1, 7, 107, 749
973 : 1, 7, 139, 973
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,351,749,973,946, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
351:3x 3x 3x 13
749:7x 107
973:7x 139
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 13 = 1001
Therefore, the value for common factors is 1001.
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 = 173021053735530/(1x1001)
LCM = 173021053735530/1001
LCM = 172848205530
Thus, we can understand that the LCM of 715,351,749,973,946 is 172848205530.
