Given numbers are 715,968,772,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,968,772,851 is 10334169560.
Find LCM of 715,968,772,851 with Prime Factorization
| 2 | 715, 968, 772, 851 |
| 2 | 715, 484, 386, 851 |
| 11 | 715, 242, 193, 851 |
| 65, 22, 193, 851 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 65 x 22 x 193 x 851 = 10334169560
Therefore, the lowest common multiple of 715,968,772,851 is 10334169560.
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 968 x 772 x 851 = 454703460640
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
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
772 : 1, 2, 4, 193, 386, 772
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,968,772,851, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
968:2x 2x 2x 11x 11
772:2x 2x 193
851:23x 37
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 11 = 44
Therefore, the value for common factors is 44.
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 = 454703460640/(1x44)
LCM = 454703460640/44
LCM = 10334169560
Thus, we can understand that the LCM of 715,968,772,851 is 10334169560.
