Find LCM of 755,736,126,672 with Prime Factorization
| 2 | 755, 736, 126, 672 |
| 2 | 755, 368, 63, 336 |
| 2 | 755, 184, 63, 168 |
| 2 | 755, 92, 63, 84 |
| 2 | 755, 46, 63, 42 |
| 3 | 755, 23, 63, 21 |
| 7 | 755, 23, 7, 21 |
| 755, 23, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 7 x 755 x 23 x 1 x 3 = 35007840
Therefore, the lowest common multiple of 755,736,126,672 is 35007840.
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.
755 x 736 x 126 x 672 = 47050536960
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.
755 : 1, 5, 151, 755
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,736,126,672, is 1.
Now, the common factors can be found like this.
755:5x 151
736:2x 2x 2x 2x 2x 23
126:2x 3x 3x 7
672:2x 2x 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 2x 2x 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 47050536960/(1x1344)
LCM = 47050536960/1344
LCM = 35007840
Thus, we can understand that the LCM of 755,736,126,672 is 35007840.
