Find LCM of 964,336,938,720 with Prime Factorization
| 2 | 964, 336, 938, 720 |
| 2 | 482, 168, 469, 360 |
| 2 | 241, 84, 469, 180 |
| 2 | 241, 42, 469, 90 |
| 3 | 241, 21, 469, 45 |
| 7 | 241, 7, 469, 15 |
| 241, 1, 67, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 241 x 1 x 67 x 15 = 81380880
Therefore, the lowest common multiple of 964,336,938,720 is 81380880.
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.
964 x 336 x 938 x 720 = 218751805440
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.
964 : 1, 2, 4, 241, 482, 964
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
938 : 1, 2, 7, 14, 67, 134, 469, 938
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,336,938,720, is 2.
Now, the common factors can be found like this.
964:2x 2x 241
336:2x 2x 2x 2x 3x 7
938:2x 7x 67
720:2x 2x 2x 2x 3x 3x 5
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 = 218751805440/(2x1344)
LCM = 218751805440/2688
LCM = 81380880
Thus, we can understand that the LCM of 964,336,938,720 is 81380880.
