Find LCM of 720,256,402,653,651 with Prime Factorization
2 | 720, 256, 402, 653, 651 |
2 | 360, 128, 201, 653, 651 |
2 | 180, 64, 201, 653, 651 |
2 | 90, 32, 201, 653, 651 |
3 | 45, 16, 201, 653, 651 |
15, 16, 67, 653, 217 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 15 x 16 x 67 x 653 x 217 = 109370499840
Therefore, the lowest common multiple of 720,256,402,653,651 is 109370499840.
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.
720 x 256 x 402 x 653 x 651 = 31498703953920
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.
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
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
402 : 1, 2, 3, 6, 67, 134, 201, 402
653 : 1, 653
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,256,402,653,651, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
256:2x 2x 2x 2x 2x 2x 2x 2
402:2x 3x 67
653:653
651:3x 7x 31
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 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 31498703953920/(1x288)
LCM = 31498703953920/288
LCM = 109370499840
Thus, we can understand that the LCM of 720,256,402,653,651 is 109370499840.
