Given numbers are 157,801,785,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,801,785,178 is 1257570.
Find LCM of 157,801,785,178 with Prime Factorization
| 89 | 157, 801, 785, 178 |
| 157 | 157, 9, 785, 2 |
| 1, 9, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
89 x 157 x 1 x 9 x 5 x 2 = 1257570
Therefore, the lowest common multiple of 157,801,785,178 is 1257570.
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.
157 x 801 x 785 x 178 = 17572025610
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.
157 : 1, 157
801 : 1, 3, 9, 89, 267, 801
785 : 1, 5, 157, 785
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,801,785,178, is 1.
Now, the common factors can be found like this.
157:157
801:3x 3x 89
785:5x 157
178:2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
89x 157 = 13973
Therefore, the value for common factors is 13973.
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 = 17572025610/(1x13973)
LCM = 17572025610/13973
LCM = 1257570
Thus, we can understand that the LCM of 157,801,785,178 is 1257570.
