Find LCM of 784,668,966,242,912 with Prime Factorization
| 2 | 784, 668, 966, 242, 912 |
| 2 | 392, 334, 483, 121, 456 |
| 2 | 196, 167, 483, 121, 228 |
| 2 | 98, 167, 483, 121, 114 |
| 3 | 49, 167, 483, 121, 57 |
| 7 | 49, 167, 161, 121, 19 |
| 7, 167, 23, 121, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 7 x 167 x 23 x 121 x 19 = 20769239568
Therefore, the lowest common multiple of 784,668,966,242,912 is 20769239568.
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 668 x 966 x 242 x 912 = 111655431917568
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
668 : 1, 2, 4, 167, 334, 668
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
242 : 1, 2, 11, 22, 121, 242
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,668,966,242,912, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
668:2x 2x 167
966:2x 3x 7x 23
242:2x 11x 11
912:2x 2x 2x 2x 3x 19
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 2x 2x 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 111655431917568/(2x2688)
LCM = 111655431917568/5376
LCM = 20769239568
Thus, we can understand that the LCM of 784,668,966,242,912 is 20769239568.
