Given numbers are 661,398,723,688,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,398,723,688,796 is 65430655536.
Find LCM of 661,398,723,688,796 with Prime Factorization
| 2 | 661, 398, 723, 688, 796 |
| 2 | 661, 199, 723, 344, 398 |
| 199 | 661, 199, 723, 172, 199 |
| 661, 1, 723, 172, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 199 x 661 x 1 x 723 x 172 x 1 = 65430655536
Therefore, the lowest common multiple of 661,398,723,688,796 is 65430655536.
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.
661 x 398 x 723 x 688 x 796 = 104165603613312
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.
661 : 1, 661
398 : 1, 2, 199, 398
723 : 1, 3, 241, 723
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
796 : 1, 2, 4, 199, 398, 796
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,398,723,688,796, is 1.
Now, the common factors can be found like this.
661:661
398:2x 199
723:3x 241
688:2x 2x 2x 2x 43
796:2x 2x 199
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 2x 199 = 1592
Therefore, the value for common factors is 1592.
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 = 104165603613312/(1x1592)
LCM = 104165603613312/1592
LCM = 65430655536
Thus, we can understand that the LCM of 661,398,723,688,796 is 65430655536.
