Find LCM of 847,294,826,692,168 with Prime Factorization
| 2 | 847, 294, 826, 692, 168 |
| 2 | 847, 147, 413, 346, 84 |
| 3 | 847, 147, 413, 173, 42 |
| 7 | 847, 49, 413, 173, 14 |
| 121, 7, 59, 173, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 121 x 7 x 59 x 173 x 2 = 1452415272
Therefore, the lowest common multiple of 847,294,826,692,168 is 1452415272.
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.
847 x 294 x 826 x 692 x 168 = 23912565038208
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.
847 : 1, 7, 11, 77, 121, 847
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
826 : 1, 2, 7, 14, 59, 118, 413, 826
692 : 1, 2, 4, 173, 346, 692
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,294,826,692,168, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
294:2x 3x 7x 7
826:2x 7x 59
692:2x 2x 173
168:2x 2x 2x 3x 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 3x 7x 7x 7 = 16464
Therefore, the value for common factors is 16464.
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 = 23912565038208/(1x16464)
LCM = 23912565038208/16464
LCM = 1452415272
Thus, we can understand that the LCM of 847,294,826,692,168 is 1452415272.
