Given numbers are 649,784,113,847,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,784,113,847,129 is 81587119152.
Find LCM of 649,784,113,847,129 with Prime Factorization
| 7 | 649, 784, 113, 847, 129 |
| 11 | 649, 112, 113, 121, 129 |
| 59, 112, 113, 11, 129 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 59 x 112 x 113 x 11 x 129 = 81587119152
Therefore, the lowest common multiple of 649,784,113,847,129 is 81587119152.
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.
649 x 784 x 113 x 847 x 129 = 6282208174704
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.
649 : 1, 11, 59, 649
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
113 : 1, 113
847 : 1, 7, 11, 77, 121, 847
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,784,113,847,129, is 1.
Now, the common factors can be found like this.
649:11x 59
784:2x 2x 2x 2x 7x 7
113:113
847:7x 11x 11
129:3x 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 11 = 77
Therefore, the value for common factors is 77.
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 = 6282208174704/(1x77)
LCM = 6282208174704/77
LCM = 81587119152
Thus, we can understand that the LCM of 649,784,113,847,129 is 81587119152.
