Given numbers are 369,709,611,639,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 369,709,611,639,128 is 1452720716928.
Find LCM of 369,709,611,639,128 with Prime Factorization
| 3 | 369, 709, 611, 639, 128 |
| 3 | 123, 709, 611, 213, 128 |
| 41, 709, 611, 71, 128 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 41 x 709 x 611 x 71 x 128 = 1452720716928
Therefore, the lowest common multiple of 369,709,611,639,128 is 1452720716928.
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.
369 x 709 x 611 x 639 x 128 = 13074486452352
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.
369 : 1, 3, 9, 41, 123, 369
709 : 1, 709
611 : 1, 13, 47, 611
639 : 1, 3, 9, 71, 213, 639
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 369,709,611,639,128, is 1.
Now, the common factors can be found like this.
369:3x 3x 41
709:709
611:13x 47
639:3x 3x 71
128:2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 13074486452352/(1x9)
LCM = 13074486452352/9
LCM = 1452720716928
Thus, we can understand that the LCM of 369,709,611,639,128 is 1452720716928.
