Find LCM of 980,945,794,320,607 with Prime Factorization
| 2 | 980, 945, 794, 320, 607 |
| 2 | 490, 945, 397, 160, 607 |
| 5 | 245, 945, 397, 80, 607 |
| 7 | 49, 189, 397, 16, 607 |
| 7, 27, 397, 16, 607 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 27 x 397 x 16 x 607 = 102020869440
Therefore, the lowest common multiple of 980,945,794,320,607 is 102020869440.
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.
980 x 945 x 794 x 320 x 607 = 142829217216000
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
794 : 1, 2, 397, 794
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
607 : 1, 607
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,945,794,320,607, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
945:3x 3x 3x 5x 7
794:2x 397
320:2x 2x 2x 2x 2x 2x 5
607:607
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 5x 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 142829217216000/(1x1400)
LCM = 142829217216000/1400
LCM = 102020869440
Thus, we can understand that the LCM of 980,945,794,320,607 is 102020869440.
