Find LCM of 641,746,128,752,268 with Prime Factorization
| 2 | 641, 746, 128, 752, 268 |
| 2 | 641, 373, 64, 376, 134 |
| 2 | 641, 373, 32, 188, 67 |
| 2 | 641, 373, 16, 94, 67 |
| 641, 373, 8, 47, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 641 x 373 x 8 x 47 x 67 = 96371693696
Therefore, the lowest common multiple of 641,746,128,752,268 is 96371693696.
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.
641 x 746 x 128 x 752 x 268 = 12335576793088
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.
641 : 1, 641
746 : 1, 2, 373, 746
128 : 1, 2, 4, 8, 16, 32, 64, 128
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,746,128,752,268, is 1.
Now, the common factors can be found like this.
641:641
746:2x 373
128:2x 2x 2x 2x 2x 2x 2
752:2x 2x 2x 2x 47
268:2x 2x 67
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 2 = 128
Therefore, the value for common factors is 128.
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 = 12335576793088/(1x128)
LCM = 12335576793088/128
LCM = 96371693696
Thus, we can understand that the LCM of 641,746,128,752,268 is 96371693696.
