Given numbers are 784,774,877,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,774,877,172 is 266088816.
Find LCM of 784,774,877,172 with Prime Factorization
| 2 | 784, 774, 877, 172 |
| 2 | 392, 387, 877, 86 |
| 43 | 196, 387, 877, 43 |
| 196, 9, 877, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 196 x 9 x 877 x 1 = 266088816
Therefore, the lowest common multiple of 784,774,877,172 is 266088816.
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.
784 x 774 x 877 x 172 = 91534552704
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
877 : 1, 877
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,774,877,172, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
774:2x 3x 3x 43
877:877
172:2x 2x 43
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 43 = 344
Therefore, the value for common factors is 344.
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 = 91534552704/(1x344)
LCM = 91534552704/344
LCM = 266088816
Thus, we can understand that the LCM of 784,774,877,172 is 266088816.
