Given numbers are 705,957,692,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,957,692,435 is 155627340.
Find LCM of 705,957,692,435 with Prime Factorization
| 3 | 705, 957, 692, 435 |
| 5 | 235, 319, 692, 145 |
| 29 | 47, 319, 692, 29 |
| 47, 11, 692, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 29 x 47 x 11 x 692 x 1 = 155627340
Therefore, the lowest common multiple of 705,957,692,435 is 155627340.
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.
705 x 957 x 692 x 435 = 203093678700
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
957 : 1, 3, 11, 29, 33, 87, 319, 957
692 : 1, 2, 4, 173, 346, 692
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,957,692,435, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
957:3x 11x 29
692:2x 2x 173
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 29 = 1305
Therefore, the value for common factors is 1305.
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 = 203093678700/(1x1305)
LCM = 203093678700/1305
LCM = 155627340
Thus, we can understand that the LCM of 705,957,692,435 is 155627340.
