Find LCM of 984,771,692,343,784 with Prime Factorization
| 2 | 984, 771, 692, 343, 784 |
| 2 | 492, 771, 346, 343, 392 |
| 2 | 246, 771, 173, 343, 196 |
| 3 | 123, 771, 173, 343, 98 |
| 7 | 41, 257, 173, 343, 98 |
| 7 | 41, 257, 173, 49, 14 |
| 41, 257, 173, 7, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 41 x 257 x 173 x 7 x 2 = 30012242064
Therefore, the lowest common multiple of 984,771,692,343,784 is 30012242064.
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.
984 x 771 x 692 x 343 x 784 = 141177586669056
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
771 : 1, 3, 257, 771
692 : 1, 2, 4, 173, 346, 692
343 : 1, 7, 49, 343
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,771,692,343,784, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
771:3x 257
692:2x 2x 173
343:7x 7x 7
784:2x 2x 2x 2x 7x 7
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 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 141177586669056/(1x4704)
LCM = 141177586669056/4704
LCM = 30012242064
Thus, we can understand that the LCM of 984,771,692,343,784 is 30012242064.
