Given numbers are 128,252,452,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,252,452,553 is 71987328.
Find LCM of 128,252,452,553 with Prime Factorization
| 2 | 128, 252, 452, 553 |
| 2 | 64, 126, 226, 553 |
| 7 | 32, 63, 113, 553 |
| 32, 9, 113, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 32 x 9 x 113 x 79 = 71987328
Therefore, the lowest common multiple of 128,252,452,553 is 71987328.
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.
128 x 252 x 452 x 553 = 8062580736
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
452 : 1, 2, 4, 113, 226, 452
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,252,452,553, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
252:2x 2x 3x 3x 7
452:2x 2x 113
553:7x 79
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 7 = 112
Therefore, the value for common factors is 112.
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 = 8062580736/(1x112)
LCM = 8062580736/112
LCM = 71987328
Thus, we can understand that the LCM of 128,252,452,553 is 71987328.
