The LCM of 973,784,905,724 is 98623280.
Find LCM of 973,784,905,724 with Prime Factorization
| 2 | 973, 784, 905, 724 |
| 2 | 973, 392, 905, 362 |
| 7 | 973, 196, 905, 181 |
| 181 | 139, 28, 905, 181 |
| 139, 28, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 181 x 139 x 28 x 5 x 1 = 98623280
Therefore, the lowest common multiple of 973,784,905,724 is 98623280.
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.
973 x 784 x 905 x 724 = 499822783040
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.
973 : 1, 7, 139, 973
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
905 : 1, 5, 181, 905
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,784,905,724, is 1.
Now, the common factors can be found like this.
973:7x 139
784:2x 2x 2x 2x 7x 7
905:5x 181
724:2x 2x 181
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 7x 181 = 5068
Therefore, the value for common factors is 5068.
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 = 499822783040/(1x5068)
LCM = 499822783040/5068
LCM = 98623280
Thus, we can understand that the LCM of 973,784,905,724 is 98623280.
