Find LCM of 784,112,830,665,707 with Prime Factorization
| 2 | 784, 112, 830, 665, 707 |
| 2 | 392, 56, 415, 665, 707 |
| 2 | 196, 28, 415, 665, 707 |
| 2 | 98, 14, 415, 665, 707 |
| 5 | 49, 7, 415, 665, 707 |
| 7 | 49, 7, 83, 133, 707 |
| 1, 7, 83, 19, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 1 x 7 x 83 x 19 x 101 = 624365840
Therefore, the lowest common multiple of 784,112,830,665,707 is 624365840.
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 112 x 830 x 665 x 707 = 34265197299200
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
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
830 : 1, 2, 5, 10, 83, 166, 415, 830
665 : 1, 5, 7, 19, 35, 95, 133, 665
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,112,830,665,707, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
112:2x 2x 2x 2x 7
830:2x 5x 83
665:5x 7x 19
707:7x 101
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 2x 2x 5x 7x 7x 7 = 54880
Therefore, the value for common factors is 54880.
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 = 34265197299200/(1x54880)
LCM = 34265197299200/54880
LCM = 624365840
Thus, we can understand that the LCM of 784,112,830,665,707 is 624365840.
