Find LCM of 672,736,865,924 with Prime Factorization
| 2 | 672, 736, 865, 924 |
| 2 | 336, 368, 865, 462 |
| 2 | 168, 184, 865, 231 |
| 2 | 84, 92, 865, 231 |
| 2 | 42, 46, 865, 231 |
| 3 | 21, 23, 865, 231 |
| 7 | 7, 23, 865, 77 |
| 1, 23, 865, 11 |
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 1 x 23 x 865 x 11 = 147063840
Therefore, the lowest common multiple of 672,736,865,924 is 147063840.
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.
672 x 736 x 865 x 924 = 395307601920
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.
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
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
865 : 1, 5, 173, 865
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,736,865,924, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
736:2x 2x 2x 2x 2x 23
865:5x 173
924:2x 2x 3x 7x 11
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 = 395307601920/(1x2688)
LCM = 395307601920/2688
LCM = 147063840
Thus, we can understand that the LCM of 672,736,865,924 is 147063840.
