Given numbers are 155,785,392,157
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,785,392,157 is 9539320.
Find LCM of 155,785,392,157 with Prime Factorization
| 5 | 155, 785, 392, 157 |
| 157 | 31, 157, 392, 157 |
| 31, 1, 392, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 157 x 31 x 1 x 392 x 1 = 9539320
Therefore, the lowest common multiple of 155,785,392,157 is 9539320.
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.
155 x 785 x 392 x 157 = 7488366200
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.
155 : 1, 5, 31, 155
785 : 1, 5, 157, 785
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,785,392,157, is 1.
Now, the common factors can be found like this.
155:5x 31
785:5x 157
392:2x 2x 2x 7x 7
157:157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 157 = 785
Therefore, the value for common factors is 785.
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 = 7488366200/(1x785)
LCM = 7488366200/785
LCM = 9539320
Thus, we can understand that the LCM of 155,785,392,157 is 9539320.
